Water is pumped at the rate of 0.075 m3/s from a

reservoir 20 m above a pump to a free discharge 35 m above

the pump. The pressure on the intake side of the pump is

150 kPa and the pressure on the discharge side is 450 kPa.

All pipes are commercial steel of 15 cm diameter. Determine

(a) the head supplied by the pump and (b) the total head loss

between the pump and point of free discharge.
