What affects NPSH? CHANGES THAT AFFECT NPSH Source Liquid Level – Changes in the liquid level feeding to the pump will affect NPSH. A raised liquid level in the tank will increase NPSHA, while a lower than expected liquid level will cause NPSHA issues. How can we reduce Npsha? The NPSHr can be reduced through […]

What happens to a container of gas when the pressure is increased? If the amount of gas in a container is increased, the volume increases. If the amount of gas in a container is decreased, the volume decreases. If you heat a gas you give the molecules more energy so they move faster. This means […]

What happens to the resistance when the length of the conductor is doubled without affecting the thickness of the conductor? what happens to the resistance when length of conductor is doubled without affecting the thickness of conductor? R = ρl/A. According to this relation, resistance is directly proportional to length of the conductor. Hence, when […]

Is it okay to add too much Dechlorinator? I’ve never heard of adding too much. But it shouldn’t be a problem, just follow the directions on the back of any dechlorinator and you’ll be fine. Nothing to worry about, unless you for some reason accidentally spill an entire bottle into the tank. Can you do […]

Does a step up transformer have more windings? A transformer that increases the voltage from primary to secondary (more secondary winding turns than primary winding turns) is called a step-up transformer. Conversely, a transformer designed to do just the opposite is called a step-down transformer. What is the turns ratio of a transformer What can […]

Is 100 yuan a lot of money? During my stay in Beijing, I’ve quickly found that one of the greatest parts of the city is the amount of fun you can have without breaking your bank. One hundred yuan, the equivalent of about $14.50 USD, goes much further here than most other cities in the […]

Take notes about error messages. If your computer gives you an error message, be sure to write down as much information as possible. Always check the cables. Restart […]

What does lava do to humans? Most lava is very hot—about 2,000 degrees Fahrenheit. At those temperatures, a human would probably burst into flames and either get extremely serious burns or die. Can lava Be Stopped? There is no way to stop the flow of lava, scientists say. They did, however, have some success in […]
