Answer:
An engine can pump 30000 litres of water to a vertical height of 25 m
in 5 minutes.
Explanation:
we all know that:
MASS OF WATER =30,000 L
HEIGHT OF THE PIPE =25m
GRAVITATION FORCE=9.8m/s
Work done, W= mgh
W= 30,000 x 9.8 x 25
= 73,50,000J
ALSO we known that
WORK DONE=73,50,000J
TIME TAKEN=5min
Power of the engine P = work done/ time taken
=73,50,000/10×60
=12,250 watts
