8. A heat pump cycle is used to maintain the interior space of a building at 21 C. At steady state, the working fluid received energy by heat transfer from a reservoir of well water at 9 C and the working fluid discharges energy by heat transfer to the interior space at a rate of 120,000 kJ/hour. After a 14 day period, the heat pump system electrical meter indicates that there were 1490 kW-hr of energy consumed. (a) What is the energy transferred into the working fluid from the well water reservoir over this 14 day period? (b) What is the COP for this heat pump process over this period? (c) What is the COP for an ideal heat pump under these conditions?
