A cylindrical settling tank with a diameter of 1 m is used to separate oil from water. Following phase separation, the water must be pumped from the settling tank to an elevated cylindrical reservoir with a diameter of 2 m. The specific gravity of the oil is 0.85. Initially, the settling tank is filled with equal amounts of water and oil (see figure). Given a pump power of 148 W, calculate how long it will take to transfer all the water from the settling tank to the reservoir. Neglect friction in the pipes and obstacles and assume that both tanks are opened to the atmosphere.
The question belongs to Chemistry and it discusses about calculating the time it takes to transfer all the water from one tank to another tank, with power to pump out water given.
