Air enters the compressor of a gas turbine plant operating on Brayton cycle at 1 bar and 27°C. The pressure ratio in the cycle is 6. If the relation between the turbine work WT and compressor work WC is WT = 3WC and γ = 1.4, the cycle efficiency will be nearly
In a two-stage air compressor, an intercooler is placed
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
