Question

The point where the fluid comes to rest is called as ___________

(a) Rest point

(b) Stagnation point

(c) Viscous point

(d) Boundary layer point

The question was asked in homework.

I'm obligated to ask this question of Bernoulli’s Equation topic in portion Inviscid & Incompressible Flow of Aerodynamics

Answer 1

Right answer is (b) Stagnation point

To elaborate: Stagnation point is the point where the flow slows down and come to rest. The streamline divides the flow into two parts- the upper flow and the lower flow. At a point, the flow cannot enter into an object so it has to stop and that point is called a stagnation point.
