the largest velocity which allows a steady flow of a fluid is called critical velocity.
significance: if velocity of a flow of a liquid exceeds the velocity corresponding to its reynolds number.N=(pvd)/n,then turbulent motion sets and the flow is no more laminar.
p=density of the fluid.
v=velocity of the fluid.
D=diameter of the tube.
n=viscosity of the fluid.
