Question: qc9 the compressor and turbine of a simple gas turbine...

Question details

QC9 The compressor and Turbine of a simple gas turbine each have isentropic efficiencies of 90%. The compressor pressure ratio is 14, The minimum and maximum temperatures are 300 K and 1500 K, respectively. On the basis of an air- standard analysis and using the air property tables provided, detemine (a) The Isentropic Heat Drop in the Turbine (b) The Actual Heat Drop in the Turbine (c) The Thermal Efficiency of an Isentropic Brayton cycle under these conditions (d) The Thermal Efficiency of the actual cycle (6 marks) (4 marks) (5 marks) (5 marks) Equations to note: (hs - h2)
