Seawater

is to be pumped into a large tank at a rate of 165 kg/min. The tank is open to

the atmosphere and the water enters the tank from a 80-m-height. The overall

efficiency of the motor-pump unit is 75 percent and the motor consumes

electricity at a rate of 3.2 kW. Take the correction factor to be 1. If the

irreversible head loss in the piping is 7 m, the velocity of the water at the

tank inlet is
