1) An equimolar mixture of helium (He) and argon (Ar) is to be used as the working fluid in a closed-loop gas turbine cycle. The mixture enters the turbine at 2.5MPa and 1300K and expands isentropically to a pressure of 200kPa. Determine the work output of the turbine per unit mass of the mixture. You are given the following equations to use (xis mass fraction of component): с рет = pm = x,cp+X,Cp2 : Cm = x,C1 + x, 2 ; k = C TP.(-k)/k = T,P,0-k)/* CV (kJ/kg/K) 0.3122 3.1156 Gp (kJ/kg/K) 0.5203 5.1926 Molar Mass, M (kg/kmol) 39.948 4.003 Argon Helium
