A pump on the ground floor of a building can pump up water to fill a tank of volume 30 m3 in 15 min. If the tank is 40 m above the ground, and the efficiency of the pump is 30%, how much electric power is consumed by the pump?

Step 1
Given density of water, \( \rho = 10 \, \text{g/ml} = 10^3 \, \text{kg/m}^3 \) Volume of water in the tank, \( V = 30 \, \text{m}^3 \) Mass of water, \( m = \rho \times V = 10^3 \times 30 = 30000 \, \text{kg} \) Show more…
