1. Assume a cyclic machine that exchanges 6 kW with a 250â—¦C reservoir and has
![]()
and
. Â L is exchanged with a 30â—¦C 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.
2. Consider a heat engine and heat pump connected as shown in Fig. P5.41. Assume that TH 1 = TH2 > Tamb and determine for each of the three cases if the setup satisfies the first law and/or violates the second law.
