(5). The compressor of an open-cycle gas turbine unit receives air at 100kPa, 18°C and delivers it at 400kPa, 200°C to the combustion chamber, where the temperature is raised at constant pressure to 650°C. The hot gases pass through the turbine having an isentropic efficiency of 85% and exhaust of 100kPa. Calculate: (a). the isentropic efficiency of the compressor (b). the net work per kg of air For air: For gas: Y = 1.4 Y = 1.333 ©p= I.005kJ/kgK = = 1.150kJ/kgK
