In laminar flow of fluid, the velocity of the fluid in contact with the walls of the tube is

In turbulent flow the velocity of the liquid molecules in contact with the walls of the tube.

In turbulent flow the velocity of the liquid molecules in contact with the walls of the tube.

In turbulent flow the velocity of the liquid molecules in contact with the walls of the tube.

A fluid is flowing through a tube of length L. The radius of the tube is r and the velocity of the fluid is v. If the radius of the tube is increased to 2r, then what will be the new velocity?

In a streamline (laminar flow) the velocity of flow at any point in the liquid

In a steady flow velocity of the fluid at each point remains identical with time .

For flow of a fluid to be turbulent
