A pump is a device that raises the pressure of a liquid at the expense of external work.
(a) Determine the pumping power necessary to raise the pressure of liquid water from 10 kPa to 2000 kPa at a flow rate of 1000 L/min. Assume density of water to be 1000 kg/m3 and neglect changes in specific internal, kinetic and potential energies.
(b) What-if Scenario: What would the pumping power be if pe were not negligible and z1 = -10, z2 = 0?
