Steady or Streamline Flow

Water is flowing through a very narrow tube. The velocity of water below which the flow remains a streamline flow is known as

The flow of a fluid in a tube is laminar or turbulent is determined by

In the case of flow of a liquid through a tube, if the Reynold's number is less than$2000$, the flow is

What are laminar flow and velocity profile ? Draw the velocity profiles for the laminar flow of a liquid

flowing over a solid surface.

What are laminar flow and velocity profile ? Draw the velocity profiles for the laminar flow of a liquid

flowing through a tube and

State the characteristics of streamline motion. When does a streamline motion turn into turbulent motion? Give a common example of it.

Why does a flag flutter in a windy day?

What is a tube of flow ? Why liquid particles of two adjacent tubes of flow cannot mix with each other?

What is a streamline ? Why two streamlines cannot intersect?

What are streamline motion and turbulent motion of a fluid?

Under a pressure difference $p$ the rate of flow of water through a capillary tube of length $l$ and radius $r$ is $I_F$. If instead of this tube, a set of four tubes each of length $2l$ and radius $\frac{r}{2}$ is connected to the same pressure difference, the rate of flow of water would be
