Step-by-step explanation:
Assuming density of water as 1, the mass of water is 100L water is 100kg. Also, assuming that there is a 90° lift, then force acting against weight is gravity.
So, F = mg or F = 100×9.81 = 981N.
The weight is raised by a height of 200metres in 1 minute.
We know that, work = force × displacement×sin(k).
Since, we assumed vertical lift, k = 90°, so
work = 981×200 = 196200 Joules. Or 196kJ.
The power would be work per unit time, which is 196000/60 = 3.270kW.
