Provided Answer is: 155 kW

8.5.11 WP A motor-driven centrifugal pump delivers \( 15^{\circ} \mathrm{C} \) water at the rate of \( 10 \mathrm{~m} 3 / \mathrm{min} \) from a reservoir, through a 2500-m-long, 30-cm I.D. plastic pipe, to a second reservoir. The water level in the second reservoir is \( 40 \mathrm{~m} \) above the water level in the first reservoir. The pump efficiency is \( 75 \% \). Find the motor output power. The pipe entrance is square edged.
