Question

__________ is referred as the temperature at a stagnation point in the flow of fluids in fluid mechanics and thermodynamics.

(a) Absolute temperature

(b) Maximum temperature

(c) Stagnation temperature

(d) Hydraulic temperature

The question was posed to me in an interview.

My doubt is from Stagnation Properties topic in section Compressible Flow of Fluid Mechanics

Answer 1

Correct choice is (c) Stagnation temperature

For explanation I would say: Stagnation temperature is the temperature at the stagnation point of the flow of fluids. In thermodynamics and fluid mechanics, these terms find application. At a stagnation point the speed of the fluid is zero and all of the kinetic energy has been converted to internal energy and is added to the local static enthalpy.
