Pumps overview
A pump is a device used to move gases, liquids, or slurries. A pump moves liquids or gases from lower pressure to higher pressure, and overcomes this difference in pressure by adding energy to the system (such as a water system). A gas pump is generally called a compressor, except in very low pressure-rise applications, such as in heating, ventilating, and air-conditioning, the equipment is known as fans or blowers. The earliest pump was described by Archimedes in the 3rd century BC and is known as the Archimedes screw pump. Pumps work by using mechanical forces to push the material, either by physically lifting, or by the force of compression. Pumps fall into three categories: positive...
Turbopumps
As the name suggests, a turbopump comprises basically two main components: a pump and a driving turbine, both mounted on the same shaft. A turbopump can refer to either of two types of pumps. Turbomolecular pumps are also called turbopumps and are used to obtain high vacuum. Another type of turbopump is a centrifugal or axial pump. Early development Turbopumps were originally developed for fire fighting for pumping water at high rates and pressures. For rocket motors, the initial breakthrough for turbopumps used in rocket motors occurred under Dr. Walter Thiel, during the development of the V2 in Germany. Prior to Dr. Thiel's work, pressurized tanks had been used. The early rocket turbopumps...
Metering pump
A Metering pump is a pump used to pump liquids at adjustable flow rates which are precise when averaged over time. Delivery of fluids in precise adjustable flow rates is sometimes called metering. The term "metering pump" is based on the application or use rather than the exact kind of pump used, although a couple types of pumps are far more suitable than most other types of pumps. Although metering pumps can pump water, they are often used to pump chemicals, solutions, or other liquids. Many metering pumps are rated to be able to pump into a high discharge pressure. They are typically made to meter at flow rates which are practically constant (when averaged over time) within a wide range of...
Circulator pump
A circulator pump is a specific type of pump used to circulate gases, liquids, or slurries in a closed circuit. They are commonly found circulating water in a hydronic heating or cooling system. Because they only circulate liquid within a closed circuit, they only need to overcome the friction of a piping system (as opposed to lifting a fluid from a point of lower potential energy to a point of higher potential energy). Circulator pumps as used in hydronic systems are usually electrically powered centrifugal pumps. As used in homes, they are often small, sealed, and rated at a fraction of a horsepower, but in commercial applications they range in size up to many horsepower and the electric motor is...
Oil Barrel Prices Continue to Climb
Oil Barrel Prices hit new World Record Highs at $76.70 and they are expected to hit $80.00 a barrel in short order and some Chicago commodity traders are thinking more like $85.00 per barrel? Can you say $4.00 per gallon gasoline prices? Could be.But why the price spikes you ask? After all there have not even been any Hurricanes in the Gulf Coast yet? Well you can expect one as early as next week, as we already have two in the Pacific right now.But also consider if you will the tensions in the Middle East between Israel, Iran, Syria, Lebanon, Palestine and the International Terrorist Groups of Hamas and Hezbollah? And also this week we see an Italian owned pipeline in Nigeria getting hit with two...

Uses of Solar Power
Solar power is a safe and popular alternative source of energy. In simple words, solar power refers to the energy generated from sunlight. There are different methods for harnessing solar energy for your day-to-day needs. In recent years, there has been increased interest and talk about the benefits of solar power. The increased interest in solar power largely due to three factors: one is our escalating energy bills, second is our depleting fossil fuel reserves, and finally the environmental impact of burning fossil fuels.Solar power addresses the concerns quite well because it uses sunlight for generating energy, which is available free, and it is harmless to the environment. This is why many...
Solar Powered Water Pumps
A great way to put solar panels to use is to install a solar powered water pump for your well. Even though windmills have more commonly been used to power water pumps, solar panels are starting to become the prefered method for pumping water in remote locations. This is great news for so many reasons. First of all, there are huge amounts of land that have been thought to be inhabitable because potable water was not available. Well, just imagine a solar well that taps deep down water sources in remote deserts all over our planet. Someday this could that overpopulation will not be a problem as vast amounts of new real estate becomes available for more and more people. Agricultural land may someday...

Dressing Well On a Budget
In order to dress well on a small budget it is important to purchase classic styles, instead of very trendy fashion pieces. Choose a combination of colors that flatters you and purchase separates in these coordinating colors. Dressing monochromatically creates an elegant look. Be sure all of your blacks or navies match completely. Classic color combinations such as brown, robin's egg blue and cream or black, beige and cream create a luxe look.Buying natural fibers is very important. Try to purchase classic styles on sale in better stores or consignment stores. Purchase cotton, silk, wool or cashmere pieces on sale or at consignment stores. Incredible buys can be found at consignment stores in...
Above Ground Pools
The ideology behind above ground pools has long been argued. A number of people suggest they seem out of place in a backyard whereas others consider them better because they are cheaper than in-ground pools. As for maintaining any artificial water body that is not cleaned of weeds and other microorganisms, sanitization of above ground pools is a common concern. When choosing an above ground pool it is important to consult professionals, who can advice potential customers regarding size, maintenance, and construction.When deciding upon an above ground pool it is advisable to select quality liners, pumps, and follow an approved excavation technique. Though most people opt for them, to avoid dealing...

Gas Stations
No other type of infrastructure was more influenced by the influx of automobiles than the gas station (also called the service station). Prior to 1910, there was little need for gas stations because ownership of cars was limited to rich hobbyists. During that time, the motorist was required to visit the local kerosene refinery found in the outskirts of the city in order to get some gasoline.When Henry Ford perfected the mass production of cars and lowered its prices in 1908, more people started owning cars. The local hardware store or carriage maker then added gas pumps to their busy central locations in the city. This arrangement did not prove beneficial, because when cars lined up to refuel, they...
Cloth Diapers
There are a wide variety of diapers available. However, although there are a variety, they can be categorized into two basic types -- disposable and cloth diapers.Parents opt for cloth diapers primarily to cut down on costs. Bringing up a baby can be a financially draining affair for many average American parents. Cotton diapers are less expensive, because they can be reused. They are usually manufactured to sustain heavy washing and are thought to be a bit better for a newborn's tender skin. However, using cloth diapers may prove to be extremely time consuming. There is the wonderful choice of opting for diaper services that are widely available across the USA. These services clean used diapers and...
Marine Electronics
Autopilots The first self-steering gear was introduced in the 1920's to control model yachts but it was not until 1948 that the principle was applied to full scale yachts. Standing at the helm for lengthy periods, monitoring instruments and keeping a good look out can be very tiring. An autopilot relieves the helmsman from steering the correct course leaving him free to maintain a proper watch. The autopilot can be set to either steer a compass course or a course relative to the wind. A fluxgate compass or electronic wind indicator feeds information to a microprocessor which then makes the necessary rudder movements to return the vessel to it's required course. The mechanical power is applied to the...

You Don't Always Get What You Want
You don't always get what you want, but do you get what you need?While pre-fishing for a tournament at Bull Shoals Lake in Missouri, we had some of the strangest things happen to us in three days there, than at any other lake we had ever been to then or since.Now don't get me wrong, we love Missouri, but this tournament and the things that happened were a nightmare. We started our drive from Delaware in 1998, (we decided to go in March to pre-fish), and we stopped at a gas station in Ohio, and not having that much experience with our trailer and new truck yet, and the excitement of the Big Bass World Championship coming up soon, momentarily clouded my perception, and we clipped the side of the pumps...
Blower Fans
Fans utilize power from a motor to generate a volumetric flow of air at a given pressure, and are considered low-pressure air pumps more often than not. A propeller converts torque (turning force) from the motor (typically permanent split capacitor AC induction motors or brushless DC) to increase static pressure across the fan rotor and to increase the kinetic energy of the air particles.Fans are classified into propeller, tube axial and vane axial styles, and each type has different characteristics. Propeller fans consist of only a motor and propeller and therefore are the simplest. Tube axial are similar to propellers but has a venturi around the propeller to reduce the vortices. Vane axial fans...
Warm Weather Alert: How to Save Money and Ensure Your Comfort with Your Home's Cooling System
Air conditioners and heat pumps are just like your car when it comes to maintenance. Both operate more efficiently and last longer if they receive scheduled care and attention. And since your cooling system makes up half of your home's utility bills, it makes sense to treat it with care. If you are a Club Member, you've already taken a step in the right direction, but there are a few other things you can do in between service calls to help your AC unit do it's best:- Clean or replace the filter once a month. As your air conditioner circulates the air in your home, dust and dirt particles collect on the filter located in the indoor unit or in the ducts. Excessive build-up forces the system to run...

Septic Systems: The Inside Story
Two ComponentsClass 4 septic systems are divided into two components, the septic tank and the septic field or leaching bed. Waste is piped out of the house into the septic tank, which is essentially a water clarification tank, in which anaerobic bacteria break the waste down into solids (sludge), liquid effluent, and scum.Septic SystemThe solids settle to the bottom, the scum floats to the top and the liquid effluent flows through an outlet pipe into a distribution chamber, where it is directed to the septic field. The septic field is an effluent water disposal system, where the liquid is channeled through perforated pipes to different parts of a field of loose gravel.Septic TankMaterials that...
The History of Wind Generated Power
With the increased costs of energy derived from fossil fuels, many consumers are interested in alternative sources of energy. Unfortunately the market trend tells us that little to no relief in oil prices is in sight. A great source of power can be harnessed from the wind using electricity generating windmills. Below is a brief history of wind power, and how it came to be.Wind power has been harnessed for many, many years. Nobody knows for sure when man started using the wind's power to grind flour or pump water, but it is thought that the first windmill appeared in the Persian region. From there this windmill technology spread back to northern Europe. Windmills crafted by the Dutch were used...

Let's face it, chairs are just too passive for their own good. High definition televisions, movie screens, the hi-fi surround sound setup that has been pain-stakingly wired and tested--these are the things that will deliver that highly-prized, streamed source of entertainment. They command great attention from prospective home theater...
Heat Pumps
Q. I've been thinking about buying a heat pump to replace my aging forced-air oil furnace. How do they work, and are they really as efficient as advertised?A. If you're shopping for a new home or looking for ways to trim costs, heat pumps can provide both heating and cooling, and in some cases, hot water heating.In areas where natural gas is not available, heat pumps are a popular alternative, but using only a heat pump for all your heating needs wouldn't be economical, or even possible. Most heat pumps use electricity as a power source, and most of them just don't cut the mustard in very cold weather. Suplementary heat such as gas, oil, electric and wood are used when the temperature falls...

Housing and Smart Houses; Energy Self Sufficient Possibilities
Housing and smart houses. I believe that we could have avoided this upcoming Natural Gas Shortage by building smarter and more efficient homes. For instance by using small devises which are simple such as using the idea of mini-hydro pumps, reflective energy boosting solar efficiency by 2.5 from a water pond (with 1-2 inches of water covered by a polymer substance of a couple of molecules and a reflective bottom surface), condensation and gravity. These small things can improve the energy efficiency by 10-fold. Here are a few things; this is how I propose which could be done.Put in a pond which has a reflective ceramic bottom and is filled with water of 2-3 inches depth out side of the house on the...

In a hot water (hydronic) heating systems, water is heated in a gas, oil, or electric boiler and circulated through pipes to convectors; older systems use radiators. When the thermostat calls for heat, a "circulator pump" in the boiler return line moves water through the pipes to the convectors, which give up heat to the rooms. When the circulator is not pumping, a "flow-control valve" stops the water flow to protect the convectors from overheating.Older gravity systems have no circulator pumps and depend on lighter, heated water rising in the pipes to the radiators; and cooler, heavier water gravitating back to the boiler.Single-pipe systems, with short branch lines to each convector, are used in...

Entrepreneur Completes Water Conservation Study
Having been in the car wash business all my life I have been overly fascinated with water, its properties, cleaning ability and abundance. But as I began my more in depth studies I learned that clean water or pure water is not quite as abundant as it should be. I completed a 2-year study on water conservation, which ended a couple of years ago. The Project started when our figures showed an impending continuation of the mild two-year drought in the mid-west and Eastern Sea Board states. We had watched the NOAA reports and foresaw a terrible situation brewing with regards to the public consumption of water and indiscriminant usage in a belief that the supply was never ending.When I set off on a 5...
Chocolate Fondue Fountain - The Night One Came To Dinner
A friend is renting a chocolate fondue fountain for her wedding, the news of which sparked off my new born interest in the phenomena that is the 'chocolate fondue fountain'. I was told that a chocolate fondue fountain can be an eye catching, mouth watering central feature for all sorts of social occasions, parties and events. This got me thinking, 'Why wait for the wedding?' So I hired a chocolate fondue fountain for a night and invited a few friends around to test it and see what all the fuss was about.We got the chocolate fondue fountain out of the box easy enough and it revealed itself to be a stainless steel structure with three tiers, with an overall height of about 15 inches top to bottom. It...

Bird Baths are available in different size and materials like glass, metal, plastics, mosaic tile, etc that can weather well and hold water.Shallow bird bath is more preferable and its surface should be rough enough so that birds can grip. Also it must have recirculating pump with filters along with water supply. The arrangement has to make such that water should be clean and clear and the maintenance of bird bath is important. The water filled in the bird bath should be clean and clear. The water should be changed routinely and in the hot weather every day it has to be changed.Bird feeders...
Vacuum Pumps
Vacuum pumps are used to pump gases out of an area, leaving a partial vacuum. The vacuum pump was invented by the German named Otto von Guericke.The flow of air removal, the amount of vacuum produced, and the power that is required to produce the vacuum are the main factors that go into choosing particular vacuum pumps. It is mandatory for manufacturers to provide information on the flow-rating availability. Standard measurements are in place to quantify how much vacuum a pump produces. This is called mmHg or HG. A lower vacuum provides high-flow pumps and a higher vacuum provides low-flow ones.Vacuum pumps have much lower power requirements than air compressors. Large-sized vacuum pumps are meant...

Heat Pumps
A heat pump is an electric cooling and heating system used to compress and decompress gas to heat or cool a house. This mechanical device pumps heat from a cooler to a warmer location and can extract heat from air, water or the earth. Heat pumps functions like an air conditioner in the summer and an electric furnace in the winter, thus encompassing both a heating and cooling unit in one device. The COP, or coefficient of performance, which calculates the ratio of heat output to electric power consumption, measures the performance of a heat pump.Heat pumps are the most resourceful form of electric heating in moderate climates, and cool a house by collecting the heat inside the house and effectively...
The Wages of Science
In the United States, Congress approved, last month, increases in the 2003 budgets of both the National Institutes of Health and National Science Foundation. America is not alone in - vainly - trying to compensate for imploding capital markets and risk-averse financiers.In 1999, chancellor Gordon Brown inaugurated a $1.6 billion program of "upgrading British science" and commercializing its products. This was on top of $1 billion invested between 1998-2002. The budgets of the Medical Research Council and the Biotechnology and Biological Sciences Research Council were quadrupled overnight.The University Challenge Fund was set to provide $100 million in seed money to cover costs related to the hiring...
