Water in a cylinder of heigth 10 ft and radius 4 ft is to be pumped out.
Find the work required if the tank is full of water and the water must be
pumped to a height 5 ft above the top of the tank
The Attempt at a Solution
I tried to slice this cylinder horizontally, so I get:
Force of gravity on slice = 62.4 * 16 * phi * delta h
Work done of slice = Force of gravity * distance
I am confused on what is the distance here, is it 5?
