Solve Problem 9.42 on a cold air-standard basis with spe- cific heats evaluated at 520R. 2 The rate of heat addition to an air-standard Brayton cycle is 3.4 X 109 Btu/h. The pressure ratio for the cycle is 14 and the minimum and maximum temperatures are 520R and 3000R, respectively. Determine the thermal efficiency of the cycle. the mass flow rate of air, in lb/h. the net power developed by the cycle, in Btu/h.
