Question
A gas-turbine power plant operates on the simple Brayton cycle with pressure ration of 16. The working fluid (air) enters the compressor at 40°C and 1 atm with a rate of 850 m³/min and leaves the turbine at 650°C. Assuming a compressor isentropic efficiency of 85 % and a turbine isentropic efficiency of 88 %. ********************************* *********** ****** Note the following: ideal gas equation of state: Pv = RT,PV = mRT, P2V2 P,V1 %3D T2 T1 k-1 T2 ideal gas undergoing an isentropic process: T1 constant specific heats and gas constant with: %3D kJ = 1.108: kg · K' kJ C, = 0.821 kg · K' kJ R = 0.287 kg · K Gp k = 1.35, Draw or calculate: (a) a "T-s" or "P-v" diagram that represents this Brayton cycle.
