Question details

wimming Pool A swimming pool has length and width of 40and 20 respectively. It has an average depth of 5. An air-to-water heat pump is used to heat the swimming pool. Water is drawn out of the swimming pool, passed through the filters and the heat pump, then returned to the swimming pool The heat pump is capable of raising the temperature of the 10 GPM water flow by 10°F. Some unit conversions and properties: GPM . gallons per minute . ft3-7.48 gallons Density of water may be taken as 62.4 lbm/ft Specific heat of water may be taken as 1 Btu/lbm °F . 1. In the spring, the owner wishes to fill the pool, then heat it to 70°F. The temperature of the pool after filling is 45°F. What is the heat input providedb the heat pump? Accounting only for the energy required to heat the water and ignoring the energy required to warm the concrete and heat losses, how many hours will it take to heat the pool?
