Chapter 9, Problem 9.65(choose chapter or problem)
On the basis of a cold air-standard analysis, show that the thermal efficiency of an ideal regenerative gas turbine can be expressed alternatively as
\(\eta=1-\left(\frac{T_{1}}{T_{3}}\right)(r)^{(k-1) / k}\)
where r is the compressor pressure ratio, \(T_{1}\) and \(T_{3}\) denote the temperatures at the compressor and turbine inlets, respectively, and as
\(\eta=1-\frac{T_{2}}{T_{3}}\)
where \(T_{2}\) is the temperature at the compressor exit.
