Question

In ________ and _______ kind of flow, the stagnation temperature is equal to the total temperature

(a) compressible, incompressible

(b) stagnated, non-stagnated

(c) dynamic, non-dynamic

(d) turbulent, passive

The question was posed to me during an internship interview.

My question is based upon Stagnation Properties topic in division Compressible Flow of Fluid Mechanics

Answer 1

Right choice is (a) compressible, incompressible

For explanation I would say: In compressible and incompressible kind of flow, the stagnation temperature is equal to the total temperature. This occurs at all points on the streamline. Eventually, this leads to the stagnation point.
