The Carrot engines A and B are operated in series. The first one, A receives heat at T_{1}(=600 K) and rejects to a reservoir at temperature T_{2}. The second engine B receives heat rejected by the first engine and, in turn, rejects to a heat reservoir at T_{3}(=400K). Calculate the temperature T_{2} if the work outputs of the two engines are equal:

a. |
400k |
b. |
600K |

c. |
500K |
d. |
300K |

w_{1}=w_{2}

u_{1}= u_{2}

T_{3} –T_{2} = T_{2}-T_{1}

2T_{2}=T_{1}+T_{3}

T_{2}=500K
