4. For a centrifugal pump operating with a characteristic curve shown in the figure below (adopted from your textbook), plot the head-discharge and power input curves, when the pump diameter is 2 m and the speed is 750 rpm. If the electricity costs $ 0.05/KWH, find the cost of pumping at the maximum efficiency.
