A pump delivers 1000 L of water into a tank at a height of 15 m in 120s.Calculate the work done by the pump and its power?(g= 9.8m/s2)
Asked by SINDHUJA SRIVASTAVA | 09 Mar, 2015, 08:29: PM
Expert Answer
Given height, h = 15 m
Mass of water = 1000 L × 1 kg/L = 1000 kg
Work done by the pump is equal the potential energy= mgh
= 1000 × 9.8 × 15
= 147 kJ
