Two carnot engines A and B are operated in series. The first one A receives heat at `900K` and rejects it to a reservoir at `T K`. The second engine B receives the heat rejected by the first engine and rejects it to a heat reservoir at `400K`. Calculate the value of `T`, when the efficiency ot two engines is the same.

Two Camot 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 :

Two carnot engines A and B are operates in series. The first one A receives heat at 800 K and rejects to a reservoir at temperature TK. The second engine B revives the heat rejected to a heat reservoir at 300 K. calculate the temperature TK for the following cases. (i) When the outputs of the two engines are equal. (ii) When the efficiencies of the two engines are equal.

Two Carnot engines A and B are operated is succession. The first one A receives heat from a source at T_(1)=800K and rejects to a sink at T_(2)K . The second engine B receives hence rejected by the first engine and rejects the another sink at T_(3) =300K. If the efficiencies of two engines are equal, then the value of T_(2) is

Two carnot engines A and B are operated in series .Engine A receives heat from a reservoier at 600 K and rejectrs heat to a reservoir at temperatures T. Engine B receives heat rejected by engine A and in turn rejects it to a reservoir at 100 K .If the efficiencies of the two engines A and B are represented by eta_(A) and eta_(B) repectively then what is the value of (eta_(B))/(eta_(A)) ?

Two Carnot engines A and B are operated in series. The engine A receives heat from the source at temperature T_1 and rejects the heat to the sink at temperature T. The second engine B receives the heat at temperature T and rejects to its sink at temperature T_(2) . For what value of T the efficiencies of the two engines are equal?

Two Carnot engines are operated in succession. The first engine receives heat from a source at T=800K and rejects to sink at T_(2)K . The second engine receives heat rejected by the first engine and rejects to another sink at T_(3)= 300K . If work outputs of the two engines are equal, then find the value of T_(2) .
