A pump helps bring oil (SG = 0.8) to reservoir D from reservoir A at 235 liters per %3D second. The energy lost from the reservoir A to the pump is 1 joule per newton and from pump to reservoir D is 3 joules per newton. If the elevation of reservoir A and reservoir D is 25 meters and 70 meters respectively, calculate the horsepower the pump supplies and the power needed if the pump is 80% efficient.
