Air enters an insulated turbine at 380 K and exits the turbine at 280 K, 100 kPa. The isentropic turbine efficiency is nturbine =0.834 and the inlet volumetric flow rate is 20 L/s. What is enthalpy at exit if the process is reversible? What would be corresponding exit temperature if the process is reversible? What is the turbine inlet pressure and the turbine (actual) specific work output (kJ/kg)?
