![]() ![]() In a Stirling cycle, the heat rejection and addition takes place at constantģ. What is the value of COP?Ī) two isothermal and two constant pressure processesī) two isothermal and two constant volume processesĬ) two isothermal and two adiabatic processesĢ. A carnot cycle refrigerator operates between 250ºK and 300ºK. If efficiency of engine is 75%, the heat rejected per cycle will beġ0. A cyclic heat engine does 50kJ of work per cycle. if temperature of high temperature reservoir is 727✬, then low temperature reservoir will have to be maintained atĩ. A carnot cycle is to be designed to attain efficiency of 0.75. If the heat loss from the house is 40kW, the power required to operate the heat pump isĨ. The outside temperature is -3✬ and the indoor temperature is 27✬. ![]() A carnot heat pump is used to heat a house. For a given temperature T1, as the difference between T1 and T2 increases, the COP of a carnot heat pumpħ. The adiabatic process of a carnot cycle needs very _ motion to complete the adiabatic process.Ħ. The isothermal process of a carnot cycle needs very _ motion of the piston to maintain constant temperature.ĥ. In a carnot cycle, the working fluid isĤ. In a carnot cycle, the working medium rejects heat at a _ temperature.ģ. In a carnot cycle, the working medium receives heat at a _ temperature.Ģ. ![]()
