Question

A point in a fluid flow where the flow has come to rest is called __________

(a) Pressure point

(b) Initial point

(c) Flow point

(d) Stagnation point

I have been asked this question during an online exam.

My query is from Newton’s Second Law in section Fluid Dynamics of Fluid Mechanics

Answer 1

Right choice is (d) Stagnation point

The best explanation: Stagnation point is a point at which a flow field of the local velocity of a fluid is equal to zero. At this point, the fluid is brought to rest by the object. When the velocity is zero, the static pressure is maximum.
