Consider a simple gas turbine (Brayton cycle) and a gas turbine with perfect regeneration. In both cycles, the pressure ratio is 8 and the ratio of specific heats of the working medium is 1.5. The ratio of minimum to maximum temperature is 0.2 (with temperature in K) in the regenerative cycle. The ratio of the thermal efficiency of the simple cycle to that of the regenerative cycle is
For the same compression ratio, the Brayton cycle efficiency is
