Thus it would require a 20 horsepower motor P in 18.182hp = P in 13.56 kW 1 hp 0.7457 kW = P in 13.558kW = P in P lift 0.30 = Since the hydraulic system is 30% efficient, the input power is: P lift 4.067 10 3 × W = P lift W pe t = t 10 sec = The lift operates in 10 seconds so the power is: W pe 4.067 10 4 × J = which yields W pe M g h = The potential energy is g 9.807
