Chapter 7, Problem 7.48(choose chapter or problem)
Real-gas behavior for turbomachinery is sometimes empirically accommodated through the expression \(\dot W= 〈Z〉 \dot W^{ig}\) , where \(\dot W^{ig}\) is the ideal-gas mechanical power and 〈Z〉 is some suitably defined average value of the compressibility factor.
(a) Rationalize this expression.
(b) Devise a turbine example incorporating real-gas behavior via residual properties, and determine a numerical value of 〈Z〉 for the example.
