An M1A1 Abrams tank operates on the simple Brayton cycle. The mass flow rate is 12 lbm/sand the compressor pressure ratio is 14. Assume that air enters at standard conditions

and the turbine inlet temperature is 2800R. (a) draw a schematic of the system (b) draw the process on a T-s diagram Using an ideal, air-standard analysis determine: (c) the heat input in Btu/hr (d) the power output in hp (e) the turbine exit temperature (EGT) (f) the thermal efficiency of the cycle
