Question

A simple ideal Brayton cycle with air as the working fluid has a pressure ratio of 10. The air enters the compressor at 300 K and the turbine at 1200 K. Determine (a) the air temperature at the compressor exit, (b) the work produced by the turbine, (c) the heat transferred in the combustor, and (d) the thermal efficiency (assuming air is an ideal gas with a constant specific heat of cv = 0.7 kJ/(kg K) and specific heat ratio k=1.4).

Step 1

The temperature at the compressor exit can be determined using the isentropic relation for an ideal gas: \[ T_2 = T_1 \left( \frac{P_2}{P_1} \right)^{\frac{k-1}{k}} \] Given: - \( T_1 = 300 \, \text{K} \) - Pressure ratio \( \frac{P_2}{P_1} = 10 \) - Specific Show more…
