Neco 2017 Agricultural Science Question 40
Practice objective / multiple choice question 40 from the 2017 Neco Agricultural Science examination.
A farmer needs to pump water from a well that is 25 m deep. The pump requires a pressure head equal to the depth plus an additional 2 m to overcome friction losses. The required flow rate is 150 L/min. The pump efficiency is 70% and water density is \(1000\,\text{kg/m}^3\). Using \(g = 9.81\,\text{m/s}^2\) and \(1\,\text{hp}=746\,\text{W}\), calculate the minimum horsepower of a diesel engine that can drive the pump.
