c. Find the temperature at the exit of the tur bine. 3) (11 pts each) Consider the heat addition or combustion portion of an ideal diesel cycle. The temperature just prior to combustion (or heat addition) is T2 = 780°F. The rate of heat addition is (170 +0.25 y ) Btu/lbm- (That is,if y = 12 then the heat addition is 173.0 Btu/lbm). Find the temperature after combustion (or heat addition.) a. Use the cold-air standard with constant specific heats. b. Use the air-standard with variable specific heats.
