Question: Matthew has been asked by Michael to find a pump to pump water from a lower reservoir to an upper reservoir that is 12 m

Matthew has been asked by Michael to find a pump to pump water from a lower reservoir to an upper reservoir that is 12 m above it at a rate of 60 L/s. He knows that the pump he is currently testing (pump 1) uses 12 kW of electricity while it's running. The other pump he tested (pump 2) has an efficiency of 70.6% and pressure difference of 118 kPa. By working out the overall efficiency and the pressure difference between the inlet and the exit of pump 1, should Matthew tell Michael to choose pump 1 or pump 2? What do you notice about the pressure difference between pump 1 and pump 2 and why do you think that is
