Consider an ideal air standard Brayton cycle in which air into the compressor is at 100 k Pa and 20^oC, and the pressure ratio across the compressor is 12:1 (r_p = P2/P1 = 12/1). The maximum temperature in the cycle is 1100^oC and air flow rate is 10 kg/sec. Assume constant specific heat for air. Determine;

(a) Work of gas turbine W_T = ?

(b) Work of compressor W_c = ?

(c) The cycle thermal efficiency  η_th= ?

(d) What is the difference between ideal Brayton cycle and actual cycle?
