A pump is used to empty the water from one cylindrical tank into another. The supply tank is 90 cm in diameter, the bottom of the tank is 1.2 m above the pump and the tank is originally filled to a level of 1.5 m. The empty receiving tank is 1.15 m in diameter and the bottom of the tank is 4 m above the pump. ... show more A pump is used to empty the water from one cylindrical tank into another.
