In a gas-turbine plant working on a Brayton Cycle, the air at the inlet of the compressor is at 25C (298.15 K) and 100 kPa. The pressure ratio (PB/PA=PC/PD) is 6.50 and the maximum permissible temperature in the turbine is 800C (1073.15 K). Consider CP = (7/2)R and CV = (5/2)R and n = 1 mol Determine the following of the ideal air cycle: (adiabatic reversible compression and adiabatic reversible expansion). Express heat and work in Joules. A. TB and TD; PB, PC, and PD for these conditions B. Heat supplied (Process BC) C. Maximum work (WSmax ), minimum work (WSmin) and Wnet
