Problem 7. The system shown in the Figure is used in the extraction of water to satisfy the needs of a population. The flow driven by the submersible pump is 1000 m3/day. The pipe used to transport the water is commercial steel with a diameter of 4 inches. As shown, a foot valve is installed on the suction side of the pump, while a check valve and 3 standard 90 long radius elbows are installed on other sections of the piping. Calculate the power that the pump must have to transport the water from the well to the storage tank. Assume the efficiency of the pump is 60% and the motor is 80%.
