Quizplus · Accepted Answer

The power needed by the pump can be calculated using the formula: Power = (density of water) * (flow rate) * (gravity) * (height). The flow rate can be calculated using the velocity and the cross-sectional area of the hose. Converting units and calculating gives approximately 2253 W.
