Question

An increase in the speed of the flow leads to an increase in kinetic energy and dynamic pressure.

(a) True

(b) False

This question was addressed to me in an online quiz.

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

Answer 1

Right choice is (a) True

To explain: An increase in speed of the flow leads to an increase in kinetic energy and dynamic pressure (0.5ρ*V^2). As the dynamic pressure increases that is the density is halved and the velocity is squared, the static pressure decreases along with the decrease in potential energy and internal energy.
