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

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

In a streamline flow, what is the velocity of the liquid in contact with the containing vessel?

In streamline flow, what is the velocity of the liquid in contact with the containing vessel?

When does the flow of the liquid become turbulent?

The liquid is flowing steadily through a tube of varying diameter. How are the velocity of liquid flow (V) in any portion and the diameter (D) of the tube in that portion are related?

Explain turbulent flow of liquids?

How is the velocity of liquid flowing through capillary tube depends?

Why does the velocity increase when liquid flowing in a wider tube enters a narrow tube ?

When a liquid moves steadily under some pressure through a horizontal tube, it moves in the form of cylindrical layers coaxial to the ends of the tube. The velocity of different layers is different. The velocity of the layer is maximum along the axis of the tube and it decreases as one moves towards the walls of the tube. According to Poiseuille, the rate of flow of liquid through a horizontal capillary tube varies as the relation V alpha (pr^(4))/(eta l) where l and r are the length and radius of the tube and p is the pressure different between the ends of the tube and is the constant of proportionality. When two capillary tubes through which the liquid is flowing are joined in series then the equivalent liquid resistance is
