definition wise i got the difference between these two efficiencies.
but in practice how does these two differ?
i was referring to this book:
Jet propulsion: a simple guide to the aerodynamics and thermodynamic design ... By N. A. Cumpsty
he has mentioned this:
"using polytropic efficiency makes algebra easier, but it also removes a bias in the isentropic efficiency when comparing machines of different pressure ratios"
can anyone please explain me in a much better way how these two efficiencies work in real practice and how they are different coz still m totally confused?
