The dynamic pressure is given by ______(a) 0.5ρ*V^2(b) ρ* V^2(c) 3*V^2(d) 5ρ* V^2I had been asked this question in quiz.This key question is from Bernoulli’s Equation topic in chapter Inviscid & Incompressible Flow of Aerodynamics

Answer»

The CORRECT option is (a) 0.5ρ*V^2

Explanation: The DYNAMIC pressure is not ACTUALLY a pressure. It simply JUSTIFIES the decrease in pressure due to the increase in the velocity. It simply justifies that when the DENSITY is half and the velocity is squared, the pressure decreases.
