A working fluid undergoes a Carnot cycle of operation. The upper absolute temperature of the fluid is θ₁
and the lower absolute temperature is θ₂. The amount of heat taken in and rejected by the workingfluids are H₁
and H₂, respectively. On account of losses of heat due to conduction etc. the heat source temperature T1 is higher than θ₁
and the heat sink temperature T₁
is lower than θ₂.
where K is some constant for both the equations, show that the efficiency of the plant is given by
