Completely solve and box the final answer. Write legibly 4. Compute the required size of the motor in Hp to drive a centrifugal pump that has a design suction pressure gage of 0.80 bar vacuum 800 mm above the pump centerline and a discharge pressure gage of 800 kpa 18.0 meters above the pump centerline. The suction pipe is 280 mm in diameter and the discharge pipe is 180 mm. A hot water at 80 degrees Celsius is pumped up at a volumetric flow rate of 8.0 m3 per minute. The pump efficiency is 80.0%.
