An irrigator desires to lift a stream of 30 lps a vertical height of 12 m. If the loss of head in the casing and pump results in a 62% over-all pump efficiency and the electric motor has an efficiency of 90%,, how many kW would a motor require in order to deliver a stream that would supply enough water in 30 hours to cover a 5-ha tract to a depth of 15 cm.?
