The polytropic or small stage efficiency of a turbine η∞, T is defined as the ratio of the actual differential work done to the isentropic differential work done by the fluid flowing through the turbine, η∞, T=d h / d hs . Consider an ideal gas with constant specific heats as the working fluid in a turbine undergoing a process in which the polytropic efficiency is constant. Show that the temperature ratio across the turbine is related to the pressure ratio across the turbine by (T2 / T1)=(P2 / P
