2.A Heat pump designer claim to have an air-source heat pump whose coefficient of preformance is 2.8 when heating a building whose interior temperature is 80 F and when the atmospheric air surrounding the building is at 10 F. is thsi claim valid ?
3.Consider a Carnot heat-engine cycle executed in a steady-flow system using steam as the working fluid. The cycle has a thermal efficiency of 35%, and steam changes from saturated vapor at 300 C during the heat addition process. If the mass flow rate of the steam is 2kg/s, determine the net power (kw) output of this engine.
