3: The pump in a water tower lifts water with a density of w = 1.00 kg/liter from a filtered pool at the bottom of the tower up hT = 37 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 lifts a volume of Vw = 5.2 liters of water up the tower every second. The water tower sits on a hill that is Te = 75 m above sea level. Let gravitational potential energy be zero at ground level. show answer No Attempt 33% Part (a) Calculate the power, Pp in Watts, of the pump. Part (b) If the pump runs for 2.5 hours, calculate the increase in the potential energy, Uw in J, of the water in the tower
