Afarmer is to pump water at 70°f from a river to a water storage tank nearby using a 125-ft-long, 5-in-diameter plasticpipe with three ﬂanged 90° smooth bends. the water velocity near the river surface is 6 ft/s, and the pipe inlet is placed inthe river normal to the flow direction of water to take advantage of the dynamic pressure. the elevation differencebetween the river and the free surface of the tank is 12 ft for a ﬂow rate of 1.5 ft3/s and an overall pump efficiency of 70percent, determine the required electric power input to the pump.
