Consider a gas turbine supplied with gas at 1000 K and 5 bar to expand adiabatically to a 1 bar. The mean specific heat at constant pressure is 1.0425 kJ/kgK and constant volume is 0.7662 kJ/kgK. Calculate power developed in kW/kg of gas per second and exhaust gas temperature
(A) 462 kW/kg and 647 K
(B) 362 kW/kg and 653 K
(C) 462. KW/kg and 653 K
(D) 362 kW/kg and 647 K
