- Published on 19 Oct 15

a. laminar velocity of fluid flow
b. turbulent velocity of fluid flow
c. critical velocity of fluid flow
d. none of the above

ANSWER: critical velocity of fluid flow
 
A liquid have steady viscous flow at only low velocity. The flow becomes turbulent after reaching certain velocity. This velocity is called as critical velocity of fluid flow.
