What is streamline flow give an example?

Streamlined flow is observed when fluid is moving with slow velocities. Water flowing slowly in a pipe and motion of spermatozoa are examples of streamline flow. Motion of water flowing in a river and motion of blood in arteries are examples of turbulent flow.

What is streamline flow and its characteristics?

The path taken by a fluid particle under a steady flow is a streamline. Properties: The tangent at any point in streamline gives the direction of the fluid velocity at that point. No two streamlines can cross.

What is streamline flow of fluids class 11?

Streamline is the path followed by the fluid particle. It means that at any particular instant the velocities of all the particles at any point are same. But the velocity of all the particles won’t be same across all the points in the space. Steady flow is termed as ‘Streamline flow’ and ‘Laminar flow’.

What is meant by streamline flow and turbulent flow of a liquid?

Laminar flow or streamline flow in pipes (or tubes) occurs when a fluid flows in parallel layers, with no disruption between the layers. Turbulent flow is a flow regime characterized by chaotic property changes. This includes rapid variation of pressure and flow velocity in space and time.

What is streamline flow and turbulent flow of fluid?

i. The smooth flow of a fluid, with velocity smaller than certain critical velocity (limiting value of velocity), is called streamline flow or laminar flow of a fluid. The irregular and unsteady flow of a fluid when its velocity increases beyond critical velocity are called turbulent flow.

What is streamline flow and turbulent flow?

Is streamline flow and laminar flow same?

In laminar flow, sometimes called streamline flow, the velocity, pressure, and other flow properties at each point in the fluid remain constant. Laminar flow over a horizontal surface may be thought of as consisting of thin layers, or laminae, all parallel to each other.

What is streamline flow and laminar flow?

What is Streamline Flow. A streamline flow is also called laminar flow, and in this flow, there are no major velocity fluctuations. A streamline is a path of imaginary particles within the fluid that are carried along with it. The streamlines are fixed in a steady flow, and fluid travels in a smooth and regular path.

What is internal flow in fluid mechanics?

Internal flow. In fluid mechanics, internal flow is a flow for which the fluid is confined by a surface. Hence the boundary layer is unable to develop without eventually being constrained. The internal flow configuration represents a convenient geometry for heating and cooling fluids used in chemical processing , environmental control,…

What is the pressure head in fluid mechanics?

In fluid mechanics, pressure head is the height of a liquid column that corresponds to a particular pressure exerted by the liquid column on the base of its container. It may also be called static pressure head or simply static head (but not static head pressure). It is mathematically expressed as:

What is Weir in fluid mechanics?

A weir is a concrete or masonry structure which is located at the bottom side (throughout width) in the path of fluid flow. The fluid (generally water) flow above the weir. A weir is generally used to regulate flow of water at a large scale, like in rivers or canals. A weir has considerable width along the length of fluid flow.

What is meant by fluid mechanics?

Fluid mechanics is a branch of physics which concerns the study of fluids and the ways in which they interact with forces. Both liquids and gases are considered to be fluids for the purposes of this branch of science.
