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.
