Consider a 5 kW heat pump working between two reservoirs at 100 C and -10 C. (a) What are QH and Q, in this

Consider a 5 kW heat pump working between two reservoirs at 100 C and -10 C. (a) What are QH and Q, in this heat pump if this pump generates 50 J/K of extra entropy per every 10 seconds? [2 Pts] (b) What is the coefficient of performance (3)? [1 Pt] (c) The heat required at the evaporator (@ -10 C) of this heat pump comes from another external reservoir at +10 C in contact with the heat pump. What is the rate of entropy generation here? [2 Pts] (d) The heat released from the working fluid in this pump is used to maintain the temperature of a water tank at 50 C. What is the rate of entropy generation here? [2 Pts] (e) Combining all information above, how much extra entropy does this cycle generate per 5 hours of operation? [1 Pt] (f) Let's say you implement a Carnot cycle in the heat pump. Can you make this process (heat pump + external reservoirs) entirely reversible while maintaining the steady-state temperatures? Why or why not? [2 Pts]
