How much heat is required to convert solid ice with a mass of 985 g and at a temperature of -29.5 °c to liquid water at a temperature of 81.5 °c? (the specific heat of ice is cice = 2100 j/kgk, the specific heat of water is cwater = 4186.8 j/kgk, and the heat of fusion for water is: lf = 334 kj/

4r-134a enters the condenser of a residential heat pump at 800 kpa and 50°c at a rate of 0.022 kg/s and leaves at 750 kpa subcooled by 3°c. the refrigerant enters the compressor at 200 kpa superheated by 4°c determine (a) the isentropic efficiency of the compressor, (b) the rate of heat supplied to the heated room, and (c) the cop of the heat pump. also, determine (d) the cop and rate of heat supplied to the heated room if this heat pump operated on the ideal vapor-compression cycle between the pressure limits of 200 and 800 kpa. (0.757, 4.37 kw, 5.12, 6.18, 3.91 kw)
