Question

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. temperatures after the compression and expansion steps

Step 1

5 and T1 = 298.15 K, and γ = 1.4 for air, we can calculate T2: \[ T2 = 298.15 \times 6.5^{(1.4-1)/1.4} = 509 \text{ K} \] Show more…
