In Rankine Cycle we use the concept of Tm(mean temperature of heat addition).In actual cycle the efficiency comes as n=1-T2/T1 Taking Tm into consideration it comes as n=1-T2/Tm as T1>Tm so the efficiency for both case will not same for a same cycle. Can anybody explain how it is possible? Advance appreciation for your effort.Thanks

In Rankine cycle there is a concept of Tm(mean temp of heat addition)For calculating the efficiency of the cycle we generally use n=1-T2/T1 again Tm taking into consideration we get n=1-T2/Tm as T1>Tm so he efficiency will be different for same cycle. Can anybody explain how is it possible? advance appriciation for your effort
