Thermodynamics Mech3001 - Week 8 - Problem 4 (9.81)

Consider a simple Brayton cycle with air as the working fluid, has a pressure ratio of 12; has a maximum cycle temperature of 600°C and operates the compressor inlet at 100 kPa and 15°C. Which will have the greatest impact on the back work ratio: a compressor isentropic efficiency of 80% or a turbine isentropic efficiency of 80%? Use constant specific heats at room temperature. Answer: 0.8387, 0.8387, the results are identical.
