A gas-turbine power plant operating on the simple Brayton cycle has a pressure ratio of 8. Air enters the compressor at 27°C and 100 kPa. The maximum cycle temperature is 1450 K. The compressor has an isentropic efficiency of 85 percent, and the turbine has an isentropic efficiency of 88 percent. Assume constant properties for air at 300 K with C = 0.718 kJ/kg · K, cp = 1.005 kJ/kg · K, R=0.287 kJ/kg · K, k = 1.4. (a) Sketch the T-s diagram for the cycle. (b) If the net power output is 170 MW, determine the volume flow rate of the air into the compressor in m³/s.

Transcribed Image Text:A gas-turbine power plant operating on the simple Brayton cycle has a pressure ratio
of 8. Air enters the compressor at 27°C and 100 kPa. The maximum cycle temperature is
1450 K. The compressor has an isentropic efficiency of 85 percent, and the turbine has an
isentropic efficiency of 88 percent. Assume constant properties for air at 300 K with
Cv = 0.718 kJ/kg • K, cp = 1.005 kJ/kg • K, R = 0.287 kJ/kg • K, k = 1.4.
(a) Sketch the T-s diagram for the cycle.
(b) If the net power output is 170 MW, determine the volume flow rate of the air into the
compressor in m³/s.
