ON TWO A gas-turbine power plant operating on the simple Brayton cycle has a pressure ratio of 7. Air enters the compressor at 0°C and 100 kPa. The maximum cycle temperature is 1227°C. The compressor has an isentropic efficiency of 80 percent, and the turbine has an isentropic efficiency of 90 percent. Assume constant properties for air at 27°C with C₂-0.718 kJ/(kg-K), Cp 1.005 kJ/(kg K), R=0.287 kJ/(kg K), y = 1.4. (a) Sketch the T-s diagram for the cycle. (b) If the net power output is 150 MW, determine the volume flow rate of the air into the compressor in m³/s

QUESTION TWO A gas-turbine power plant operating on the simple Brayton cycle has a pressure ratio of 7. Air enters the compressor at 0°C and 100 kPa. The maximum cycle temperature is 1227°C. The compressor has an isentropic efficiency of 80 percent, and the turbine has an isentropic efficiency of 90 percent. Assume constant properties for air at 27°C with C₂-0.718 kJ/(kg-K), Cp - 1.005 kJ/(kg K), R=0.287 kJ/(kg K), y = 1.4. (a) Sketch the T-s diagram for the cycle. (b) If the net power output is 150 MW, determine the volume flow rate of the air into the compressor in m³/s
