Question
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)

If there are 311 sunny days per year in Arizona, but only 160 sunny days per year in Pennsylvania, how much average power (in MW/acre) could the same PV panels generate in Pennsylvania? Please include two decimal places in your answer. Note: assume that a cloudy day delivers 0 watts/acre of solar power. This is not true, but it simplifies the problem for us.arrow_forwardQ 145.

- 4. Suppose that a nuclear power plant has an efficiency of about 0.34, and generates 1000 MW of power. It is located on the banks of a major river that is 67 m wide near the plant, approximately 3 m deep, and flows at a rate of 0.5 m/s. Suppose that the plant re-routes all of this water into the plant and dumps its waste heat evenly throughout the water, then returns the warmer water to the river. How much warmer is the river downstream of the plant compared to upstream? Water's specific heat is approximately 4184 J/kg/K, and its density is 1000 kg/m³. [Answer: The water is warmer by 4.62 K. This is a lot warmer!]arrow_forwardem 5 A NATO base in northern Norway is warmed with a heat pump that uses 7.0°C ocean water as the cold reservoir, Heat extracted from the ocean water warms fluid to 80° C; this warmed fluid is used to heat the building When the system is working at full capacity, 2000 kW of heat are delivered to the building at the cost of 600 kW of electric energy.
