The rate of heat addition to an air-standard Brayton cycle is 5.2 × 108 Btu/ h. The pressure ratio for the cycle is 12 and the minimum and maximum temperatures are 520°R and 2800°R, respectively. Determine
(a) the thermal efficiency of the cycle.
(b) the mass flow rate of air, in lb/h.
(c) the net power developed by the cycle, in Btu/h.
