Answer 1

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
