The heat input to the Brayton cycle is nearest:
The pressure and temperature at the inlet to the ideal Brayton cycle shown, are 100 kPa and 10ºC. It has a compression ratio of 8. The maximum temperature in the cycle is 1000ºC. Assume constant specific heats from Table B-2 for all
calculations.
A) 800 kJ/kg
B) 760 kJ/kg
C) 720 kJ/kg
D) 680 kJ/kg
B) 760 kJ/kg
A constant-pressure process occurs between states 2 and 3. The maximum temperature occurs at
state 3 so the heat transfer, for this constant-pressure process, is
