Question

The pressure coefficient at a stagnation point is _____

(a) +1

(b) -1

(c) 0

(d) Infinite

This question was posed to me by my college professor while I was bunking the class.

I would like to ask this question from Stagnation Properties in portion Compressible Flow of Fluid Mechanics

Answer 1

Right choice is (a) +1

For explanation: The pressure coefficient at a stagnation point is unity. This is referred to as +1. A pressure coefficient is a dimensionless number which describes the relative pressures throughout a flow field in fluid dynamics.
