Problem # 3 [30 Points] Gas Turbine Performance Air enters a
turbine at 10 MPa and 300 K and exits at 4 MPa and to 240 K.
Determine the turbine work output in kJ/kg of air flowing [a] using
the enthalpy departure chart, and assuming the ideal gas model.
Given: Air T1 = 300 K T2 = 240 K Find: w
[a] Real Gas P1 = 10 MPA P2 = 4 MPa
Ideal Gas System Schematic:
Process Diagram: Engineering Model: Property Data:
MW = 28.97 kg/kmol
h1* = 300 kJ/kg
∆h1/RTc = 0.5
Tc = 133 K
h2* = 240.2 kJ/kg
∆h2/RTc = 0.1
Pc = 37.7 bar
R = 8.314 kJ/kmol∙K
