Explanation:

18. The capacity of an overhead tank is 2400 m³. This required to be filled by a pump which required to pump water upto a height of 18 m in 40 minutes.Find the power required by the pump?

1. 176.58 kW
2. 175.00 kW
3. 172.58 kW
4. 180.58 kW

Explanation:

Volume of tank, V=2400 m3, Time, t=40 min , H=18m

Rate of discharge from pump.
Q = V/t= 2400 (m3) / (40x 60(s))
= 1m3/s

Power, = p x g x Q x H x 10 -3 kW
= 1000 x 9.81 x 1 x 18 x 10 -3 kW

= 176.58 kW

Hence, the power required by the pump is 176.58 kW.
