Hence, the pressure ratio for most effective reheat equally splits the gas turbine pressure ratio. This
results in equal work from each part of the turbine. If ε s 1 then the situation changes and the pressure
ratio has to be evaluated iteratively. The pressure ratio can also be evaluated iteratively if T

if the compressio n and expansion are not isentropic.
17.2.3.2 Optimum pressure ratio for intercooling of gas turbines
The Ts diagram for an intercooled cycle is shown in Fig. 17.16. This cycle can be analysed in a similar
way to the one with reheat to determ ine the optimum intermediate pressure for interc ooling,
