11 Examples of Laminar Flow: Detailed Explanations


Examples of laminar flow mainly found in the cases where the flow of the channel is comparatively smaller than the regular flow. In this article examples of laminar flow and its related everything is prate.

The 11+ examples of laminar flow are listed below:-

What is the meaning of laminar flow?

In the laminar flow the physical quantities remains same for this particular reason the laminar flow also called as the flow of streamline. In the laminar flow pressure, velocity and many more physical quantities remains same.

Laminar flow explain as,  the viscous fluid when flow in a motion that time the molecules of the viscous fluid can move in parallel layers at a certain time period. In the flow of the laminar velocity and pressure and other parameter of physical stays same at the each of the particles of the parallel layers.

When a viscous fluid flow is a motion through a closed system such as rod or pipe and middle of the flat plates that time flow of the laminar is appear. Laminar flow of a viscous fluid depends upon viscosity, velocity and the shape or size of the rod.

In which factors the flow of the laminar is dependent?

If we go through the law of Poiseuille then how the flow of the laminar is dependent on the physical factor easily can be understand.

The flow of laminar depends on some factors. The factors are,

Viscosity:

The flow of laminar depends on viscosity. The relationship with the flow of laminar and viscosity is indirectly proportional to each other. Means if the rate of viscosity is increases then the value of flow of laminar is decreases and if the rate of viscosity is decreases then the value of flow of laminar is increases.

Velocity:

The flow of laminar depends on velocity. The relationship with the flow of laminar and velocity is directly proportional. Means if the rate of velocity is increases then the value of flow of laminar is also increases and if the rate of velocity is decreases then the value of flow of laminar is also decreases.

Pressure:

The flow of laminar depends on pressure. The relationship with the flow of laminar and pressure is directly proportional to each other. Means if the rate of pressure is increases then the value of flow of laminar is also increases and if the rate of pressure is decreases then the value of flow of laminar is also decrease in the same way.

Size of the rod or pipe:

The flow of laminar depends on size of the rod or pipe. The relationship with the flow of laminar and size of the rod or pipe is indirectly proportional to each other. Means if the rate of size of the rod or pipe is increases then the value of flow of laminar is decreases and if the rate of size of the rod or pipe is decreases then the value of flow of laminar is increases.

The relation between Reynolds number and flow of the fluid:

Reynolds number is dimensionless physical factor. By the using Reynolds number easily can estimate the type of the flow of viscous fluid. The Reynolds number easily can understand us the flow is laminar or turbulent.

The relation between Reynolds number and flow of the fluid is given below,

Where,

Re = Reynolds number

ρ = Density for the viscous fluid

V = Characteristic velocity for the viscous fluid

L = Characteristic length for the viscous fluid

μ = Dynamic viscosity for the viscous fluid

v = Kinematic viscosity for the viscous fluid

The change of state middle of the dynamic viscosity and kinematic viscosity is given below,

v = μ/ρ

Reynolds number:-

Reynolds number can be deriving as the ratio between the inertia force and viscous force.

Mathematically Reynolds number can be written as,

Re = ρuL/μ

Where,

Re = Reynolds number

ρ = Density of the viscous fluid

u = Speed of flow of the viscous fluid

L = Characteristics linear dimension of the viscous fluid

μ = Dynamic viscosity of the viscous fluid

With the help of Reynolds number we can estimate several properties of the fluid such as viscosity, velocity, length, pressure and many others.

Aircrafts:

An aircraft is a machine or vehicle that can fly with the support of air. An aircraft can fly using the force of static lift, force of dynamic lift with the air foil. An aircraft is an example of laminar flow which we use in our practical daily life. By the help of aircraft anybody can reach to their desired place in a very short time.

Canals:

A canal is an example of laminar flow which we use in our practical daily life. Canal actually a waterway which made of artificially for transfer vehicles in the waterway or to build the management of the drainage system. Canal can carry free, in a smooth calm surface where water easily can flow under the pressure of atmospheric.

River:

A river is an example of laminar flow which we use in our practical daily life. A river is actually a natural waterway that depth can be huge or shallow. In the river the water is falls towards the downstream due to the gravitational force. A smaller size river that also known as brook, stream or creek.

Taps:

A tap is an example of laminar flow which we use in our practical daily life. When the water is comes through the tap the flow will straight there turbulence is not present. When the water is comes from taps that moment pressure and viscosity became same at each point of the water.

Tea pouring from kettle:

Tea pouring from kettle is an example of laminar flow which we are used in our practical daily life. When tea is comes through the nozzle of the kettle the flow will straight and there turbulence is not present for this reason laminar flow is appearing. When the tea is comes from kettle that moment pressure and viscosity and other parameter of physical remain same at each point of the tea.

Viscous fluid:

Every viscous fluid is an example of laminar flow which we use in our practical daily life. In every viscous fluid pressure, viscosity and other parameter of physical remain same at each point of the fluid for this reason laminar flow is appearing.

Fountains:

A fountain is an example of laminar flow which we use in our practical daily life. A fountain is actually a reservoir which is used as decoration. In the decorative reservoir mainly water is discharge. In every fountain the pressure, viscosity and other parameter of physical remain same at each point of the water for this reason laminar flow is appearing.

Smoke:

A smoke is an example of laminar flow which we produce in our practical daily life. When smoke is comes there turbulence is not present for this reason laminar flow is appearing. In smoke pressure and viscosity and other parameter of physical remain same at each point.
