Greetings everyone. Can anyone explain to me the physical significance of "Density x Velocity^2" term? What does it actually mean and what is it called? Few places it is referred as momentum flux, is there any other term for it? Thank you for your time.
Afaruque,
On youtube, search for Momentum flux equation with application.
This tutorial should help you.

Excellent tip Breizh - I find the loose use of "momentum" confusing because I can't help apply undergrad dimensional analysis and the term simply doesn't stack up when I apply basic arithmetic.
"Momentum flux" makes dimensional sense and is consistent with the theory you point to (the tutorial from Djordje Romanic was a handy refresher).
GPSA uses "velocity head" for momentum flux that is also equivalent to "dynamic pressure", as noted by Bothamley.
