Underground water is to be pumped by a 78 percent efficient 14.5-kW submerged pump to a pool whose free surface is 33.8 m above the underground water level. The diameter of the pipe is 7 cm on the intake side and 5 cm on the discharge side. The irreversible head loss of the piping system is 4.38 m.

1)Determine the flow rate of water in cubic meters per second.

2)Determine the pressure difference across the pump in kPa.
