WebUsing these efficiencies helps find the weak points of the cycle and how to use less fuel for more work. Since this cycle relies upon air as the working fluid, there is a pressure ratio that needs to be tracked throughout the cycle. Using the ideal gas law, airflow and properties are able to be fully tracked throughout the cycle. WebAir is used as the working fluid in a simple ideal Brayton cycle that has a pressure ratio of 12, a compressor inlet temperature of 300 K, and a turbine inlet temperature of 1000 K. Determine the required mass flow rate of air for a net power output of 70 MW, assuming both the compressor and the turbine have an isentropic efficiency of 85 ...
