A gas turbine engine has a pressure ratio of 9.2 to 1 and operates on an ideal Brayton cycle. Assume air enters at 25 'C and 101 kPa, and that 750 kJ/kg are added in the combustion chamber.
a. Analyze the cycle using cold air standard assuptions.
b. Analyze the cycle assuming air standard assumptions that account for variation in specific heats using your air tables.
