Question: In a gas turbine plant the intake pressure and temperature
0

are 1 bar and 18 ÂșCrespectively. The air is compressed to the pressure of 4.1 bar by a compressor, whose isentropic efficiency is 80%. The temperature of the gas, whose properties may assumed to resemble with those of air, is raised to 645ÂșC in the combustion chamber where there is a pressure drop of 0.1 bar. Expansion to atmospheric pressure then occurs. If the thermal efficiency of the plant is to be 19% what must be the isentropic efficiency of the turbine? The mass of fuel may be neglected
