The Carrot engines A and B are operated in series. The first one, A receives heat at T1(=600 K) and rejects to a reservoir at temperature T2. The second engine B receives heat rejected by the first engine and, in turn, rejects to a heat reservoir at T3(=400K). Calculate the temperature T2 if the work outputs of the two engines are equal:
a. |
400k |
b. |
600K |
c. |
500K |
d. |
300K |
