Expert Tip:Avoid operating a pump continuously at Shut Off or Run Out. These are system extremes and can lead to overheating, cavitation, or premature wear. Always aim for operation near the Best Efficiency Point (BEP). The Shape of the Curve Mostcentrifugal pumpsare characterized by an ellipt...
You can see that the fatty acids are like acetic acid, but they have much longer carbon chains. To make a normal fat, you take three fatty acids and bond them together with glycerol to form a triglyceride, like this: Since this particular triglyceride happens to contain three molecules of ...

The only problem is that no one really knows if the Hyperloop will work and how much it will actually cost. That's not stopping Musk from pushing the concept. He says the price tag is a mere $6 billion. Many people are a bit skeptical. Some experts say they couldn't build a ...
Gas pumps are one of those little things you interact with all the time, but don't know much about. Learn about gas pumps at HowStuffWorks.
But geothermal energy has the potential to do so much more than calm and captivate us: Just a few miles below the surface, the Earth’s crust has enough energy to sustain humankind for generations to come.Admittedly, the headlines have not been relaxing reading lately. From skyrocketing energy...
This information about the energy efficiency of geothermal heat pumps should by now have you asking “how much does geothermal energy cost?” Geothermal heat pump cost is initially higher than a regular heat pump, but the energy savings are rather significant. The U.S. Environmental Protection Ag...
, for example, can come with tens of thousands of dollars in upfront installation costs because it requires drilling or excavating. an air-source heat pump, meanwhile, doesn't require any excavating, but won't save you as much on your bills. "it's quite the range, ...
A skimmer is a small electronic device installed by crooks on card readers on gas pumps, ATMs and elsewhere. The skimmer reads the information from the magnetic stripe on your credit or debit card when you swipe or insert the card. They can be hard to detect, and some of the newer ones...
Diesel engines also last longer than gas engines because they run at a much slower rpm (revolutions per minute) rate than gas engines do. The hybrid diesel locomotive is an incredible display of power and ingenuity. It combines some great mechanical technology, including a huge, 12- to 16-...
