Using air as the working fluid, a simple Brayton cycle operates with minimum and maximum temperature of 27 °C and 697°C. It is operating with maximum cycle pressure 16 bar und minimum cycle pressure 1 bar. The mass flow rate is 10 kg/s. The isentropic efficiency of compressor is 80% and the isentropic efficiency of turbine is 90%. Take air as ideal gas and assume constant specific heats at room temperature. Note the following: ideal gas equation of state: Pv = RT,PV = mRT, T2 P2V2 _ P,V1 T1 k-1 ideal gas undergoing an isentropic process: constant specific heats and gas constant with: kJ Cy = 0.718; kg · K' kJ Cp = 1.005; kg · K’ kJ R = 0.287; kg · K k = 1.4, Draw or calculate: (a) a “T-s" or “P-v" diagram that represents this Brayton cycle. (b) the actual outlet temperature (K) of the compressor. (c) the actual outlet temperature (K) of the turbine.
