Solve the below problem:
Q: Assume a cyclic machine that exchanges 6 kW with a 250oC reservoir and has
a. Q.L = 0 kW, W. = 6 kW
b. Q.L = 6 kW, W. = 0 kW
and Q.L is exchanged with a 30oC ambient. What can you say about the processes in the two cases a and b if the machine is a heat engine?
Repeat the question for the case of a heat pump.
