Task A heat pump delivers 8 kJ thermal energy to the high temperature reservoir (the inside of the house). Consider the following five cases for the power consumed in the heat pump: a) W 8 k] b) W 0 kJ c) W 1 kJ d) W 0.5 kJ e) W 0.87 kJ Using the Clausius statement of the Second Law of Thermodynamics. Determine if the cycle is possible. Also, determine the cyclic heat transfer (HQ) in each case. Is there a relationship between this cyclic integral and the possibility of the cycle occurring? Homework- Clausius Inequality for a heat pump (continued): A heat pump delivers 8 kJ thermal energy to the high temperature reservoir at the temperature of 22°C (the inside of the house). The outside ambient temperature is -10°C. Determine the coefficient of performance of the Carnot heat pump cycle operating between these two thermal reservoirs. Compare the coefficient of performance of the Carnot heat pump cycle with the coefficient of performance of the cycle for each of the following five cases and determine if the cycle is possible. a) W 8 kJ b) W 0 kJ c) W 1 k d) W 0.5 kJ e) W 0.87 kJ Homework- Clausius Inequality for a heat pump (continued): Determine the cyclic integral in each case if all the processes are isothermal. Is there a relationship between this cyclic integral and the possibility of the cycle occurring? a) W 8 kJ b) W 0 kJ c) W 1 kJ d) W 0.5 kj e) W 0.87 kJ
