Air enters a 3600-kW turbine operating at steady state with a mass flow rate of 18 kg/s at 800oC, 3 bar and a velocity of 100 m/s. The air expands adiabatically through the turbine and exits at a velocity of 150 m/s. The air then enters a diffuser where it is decelerated isentropic ally to a velocity of 10 m/s and a pressure of 1 bar. Employing the ideal gas model, determine
Determine the temperature at the exit of the turbine, in K.
Determine the specific enthalpy at the exit of the diffuser, in kJ/kg.
Determine the pressure at the exit of the turbine, in bar.
Determine the rate of entropy production for the turbine, in kW/K.
