A wind mill pumps 10kg of water every minute up to a height of 5 meter. Find the power of windmill.

Given h= height = 5 m
m = mass = 10 kg
g = acceleration due to gravity =9.8
Work done by windmill = mgh
= 10 X 9.8 X 5
= 490 Joules
Power =

\frac{work done}{time taken}

\frac{490}{60}

= 8.16 watts
