Q9. A pump delivers fresh water at the rate of 32 tonne/hour. The delivery pipe is 90 mm bore. Suction is from a tank which is 0.9 m below the pump and delivery is to a tank which is 19.5 m above the pump. The discharge pipe has a total length of 25 m and has a friction factor coefficient of 0.01.

The efficiency of the pump is 75 %.

Friction losses and velocity in the suction pipe can be neglected.

Calculate EACH of the following.

(a) The total manometric head in the system; (12)

(b) The input power of the pump. (4)
