This question is concerned with air flowing through a turbine. Air expands through a turbine from 9.3 bar and 930 K, to 1.4 bar and 448.1 K; the inlet velocity is small compared to the outlet velocity of 94 m/s. The turbine operates at steady state and develops a power output of 2908 kW. Heat transfer between the turbine and surroundings and potential energy effects are negligible. The air behaves as an ideal gas with molecular weight 28.97 g/mol. You will need to use the Moran & Shapiro property tables (on Canvas). a) Using the property tables calculate the specific enthalpy of the air entering the turbine. kJ/kg (accuracy required to 0.1%)
b) Using the property tables calculate the specific enthalpy of the air leaving the turbine. kJ/kg (accuracy required to 0.1%) c) Calculate the mass flow rate of air. kg/s
