Air at 1175K, 8 bar enters a turbine operating as steady state and expands adiabatically to an exit state of 1 bar. the isentropic turbine efficiency is 92%. Employing the ideal gas model with k = 1.4 for the air, determine (a) the work developed by the turbine, in kJ per kg or air folwing, and (b) the temperature at the exit, in K. Ignore kinetic and potential energy effects.
