The Attempt at a Solution
Taking the engine to be a Carnot engine,## \eta = \frac { T_h – T_c } {T_h} = \frac { W} {Q_h} ## ...(1)
## Q_h = C(T_h – T_f) ...(2)
\\ Q_c = C(T_f – T_c) ...(3)
\\ W = Q_h – Q_c = C(T_h + T_c – 2 T_f) ## ...(4)Solving the above equations,
## T_f = \frac { 2T_c T_h }{T_h +T_c} ## ...(5)This solution does not lead me to any of the given option.
Is this correct?
