Question

The stagnation temperature To in case of an isentropic flow is the same as defined for the adiabatic flow.

(a) True

(b) False

I had been asked this question in exam.

My doubt is from Definition of Total Stagnation Conditions topic in section Compressible Flow – Preliminary Aspects of Aerodynamics

Answer 1

Correct choice is (a) True

Best explanation: Isentropic flow is a flow which is both adiabatic and reversible. In this case the resulting pressure and density are defined as the stagnation pressure and stagnation density while the stagnation temperature is the same as that of an adiabatic flow.
