the energy to lift the water is
... m g h = 10 kg * 10 m/s^2 * 10 m
... = 1000 J
the kinetic energy of the water at delivery is ... 1/2 m v^2
... = 1/2 * 10 kg * (10 m/s)^2
... = 500 J
1500 J / s = 1500 watts = 1.5 kw
Ten litre of water per second is lifted from well through 10m and delivered with a velocity of 10m/s if g=10m/s^2. The power of motor is
