A water pump in a building complex pumps water up to a height of 22.0 m at a rate of 130.0L/minute. Water has a density of 1.00kg/L a) Find the amount of energy required every minute to do this b) Use energy conservation to find the speed of the water if it then falls all the way back down the 22.0m height c) The remaining 35% of the input power ends up heating the motor and surroundings. We might want to know how much thermal energy we are adding, so that we avoid overheating the motor. What is the amount of thermal energy we generate if we run this pump for a full day? (Analgues: Betts 9-14, 9-43. Assume no air resistance for part b)

Instantaneous Power

Power is defined in physics as the amount of energy transmitted or transformed per unit time. The watt is the unit of electricity in the International System of Units, equivalent to one joule per second.
