In a gas turbine plant the hot gases from the combustion chamber pass to the turbine where they are expanded to the same pressure as the air at the compressor inlet. The compressor and turbine are directly coupled. The plant operates between pressure limits of 100kPa and 600kPa. The respective temperatures are: Compressor inlet Turbine inlet Turbine exhaust 30°C 680°C 370°C The isentropic efficiency of the compressor is 85% and y = 1.4 throughout. Calculate: (a). the temperature of the compressor outlet (b). the isentropic efficiency of the turbine

In a gas turbine plant the hot gases from the combustion chamber pass to the
turbine where they are expanded to the same pressure as the air at the
compressor inlet. The compressor and turbine are directly coupled. The plant
operates between pressure limits of 100kPa and 600kPa. The respective
temperatures are:
Compressor inlet
Turbine inlet
Turbine exhaust
30°C
680°C
370°C
The isentropic efficiency of the compressor is 85% and y = 1.4 throughout.
Calculate:
(a). the temperature of the compressor outlet
(b). the isentropic efficiency of the turbine
