Energy - ANSWERSThe ability to do work or stored work Work - ANSWERSan applying a force to something Force - ANSWERSSomething that tends to put something in motion potential energy - ANSWERSstored energy kentic energy - ANSWERSenergy in use ( kentic energy can still have stored energy) Pressure with pumps - ANSWERSPumps DO NOT create pressure, pumps create a flow Flow - ANSWERSMeasured in GPM and is the amount of water moving through a pump Head - ANSWERSHow high a pump can pump Pressure - ANSWERSIs a product of flow and resistance, measured in PSI (Pressure per squared inch) Static Pressure - ANSWERSMeasure of pressure when the fluid and the pump are not moving Dynamic Pressure - ANSWERSMeasure of pressure when the fluid and pump are moving Suction Lift - ANSWERSpump is positioned ABOVE the level of LIQUID Suction Head - ANSWERSpump is position BELOW the level of LIQUID Static Discharge Head - ANSWERSDistance between the impeller eye and the final discharge, measured in (In of FT) Static suction head - ANSWERSDistance between the pump and liquid when the pump is below the liquid Static Suction Lift - ANSWERSDistance from pump to liquid when pump is below the pump Total Static Head - ANSWERSCombined elevation of suction and discharge, Head/lift Friction Head - ANSWERSThe amount of head needed to overcome the resistance to flow in the pipe and fitting Velocity Head - ANSWERSamount of head or energy required maintain the total velo/flow in the system Total Dynamic Head - ANSWERS(TDH) includes velo and friction head to see how much head is produced. Static head + frictional loss + velo head = TDH Specific Gravity - ANSWERSA ratio to whatever is flowing against gravity. Suction Limitation - ANSWERSPump utilizes a low pressure at the suction side which lets a liquid into the pump from the pipe. This is the limit of liquid the pump can pull in. Vapor Pressure - ANSWERSan indication of liquids tendency to become a vapor Bernoulli's Law - ANSWERSVelocity and Pressure have a inverse relationship. (Pressure increases Velocity decreases and vice versa) NPSH - ANSWERSNet Positive Suction Head- combined all factors limited the suction side of the pump
