air enters a turbine operating at steady state at 8 bar, 1127 C and exits at 1.5 bar, 347 C. The heat transfer from the turbine to its surroundings is 10 kJ/kg of air flowing through the turbine. Neglecting kinetic and potential energy changes and assuming the ideal gas model for the air, determine the worked deeloped, inkJ per kg of air flowing through the turbine
