The pump in a water tower raises water with a density of rhow = 1.00 kg/liter from a filtered pool at the base of the tower up ht = 21 m to the top of the tower. the water begins at rest in the pool and comes to rest at the top of the tower. the pump is 100% efficient in lifting the water, and it raises a volume of vw = 6.2 liters of water up the tower every second. the water tower sits on a mound that is te = 75 m above sea level. let gravitational potential energy be zero at ground level.
calculate the power. pp in watts, of the pump
