There are two canot engines A and B. Engine A absorbs energy from a source at temperature `T_1` and releases energy to sink at temperature T. If engine B absorbs half of the energy released by A and B release energy to a sink at temperature `T_3`. If work done by 2 engines is same. What is T in terms of `T_1` and `T_3`

Two Carnot engines A and B operate in series such hat engine A absorbs heat at T_(1) and rejects heat to a sink at temperature T. Engine B absorbs half of the heat rejected by Engine A and rejects heat to the sink at T_(3) . When workdone in both the cases is equal, to value of T is :

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?

A Carnot enginer abosrbs an amount Q of heat from a reservoir at an absolute temperature T and rejects heat to a sink at a temperature of T//3 . The amount of heat rejects is

Efficiency of carnot heat engine,if source temperature is T1K and sink temperature is T2K
