The main waterline into a tall building has a pressure of 600 kPa at 5 m below

Question:

The main waterline into a tall building has a pressure of 600 kPa at 5 m below ground level. A pump brings the pressure up so the water can be delivered at 200 kPa at the top floor 150 m above ground level. Assume a flow rate of 10 kg/s liquid water at 10oC and neglect any difference in kinetic energy and internal energy u. Find the pump work.
