A cylindrical water tank has height 10 meters and a base radius of 3 meters. If the tank is full of water, how much work is required to pump the water out through the top? (Recall weight density of water is 1000*9.8 = 9800 N/m^3)
Explanation:
Since each slice has constant area, we could also simply take the entire volume of the water and multiply by the average distance 5 meters.
