f Efficiency. Itis now important to see how the calculation of efficiency is affectedby the adoption of a linear equation for the specific heat. Themost important cycle is the Constant volume one, and in thatit will be remembered (see par. 18) that it was found that (T— rt)—(izv- t0) * See the… … •I -2 ENTROPY Fig. 18a. With a variable specific heat the calculation of the thermalefficiency is far more complex. Thus heat taken in and heat rejected (T3—T0)[p1 + 2T0 + T3 so that (T.—T^ + s T,+T.2 {T,—T0)[$1 + s Ta + Ti Vo (To—T^ifr + s Ti + Tf where r)0 is the new efficiency. It is now…
