2. A simple-ideal Brayton cycle using air as the working fluid has a pressure ratio of 8.
The minimum and maximum air temperatures in the cycle are 300 and 1500 K
respectively. Assume constant specific heat of air at 1005 (J/kg.K) throughout the
cycle, determine:
a. The net work output.
b. The thermal efficiency.
c. The second-law efficiency of the cycle if the heat is added at 1800 K.
d. The rate of exergy loss in the cycle, if the mass flow rate is 10 kg/s.
e. The optimum pressure ratio that would produce the maximum power output
for the same temperature limits.
