The potential energy to raise the water

=  mass of water (500kg, 1 liter of water is 1 kg) x gravitational pull(10m/s) x height (40m)

500kg x 10m/s x 40m= 200000 joules (work, potential energy)

.Power = work / time

Therefore time = work 200000joules/power 1kw= 1000joules/s)

time =  200000joules/1000joulse/s

= 200000/1000 s

= 200 s
