Examples of Laminar Flow in the following topics:
-
- This is generally split into two categories, laminar and turbulent flow.
- At the lower limit of this mixed turbulent–laminar flow Reynolds number region there is another critical threshold value, below which only laminar flow is possible.
- Laminar flow consists of a regular-flow pattern with constant-flow velocity throughout the fluid volume and is much easier to analyze than turbulent flow.
- In practice, Poiseuille's equation holds for most systems involving laminar flow of a fluid, except at regions where features disrupting laminar flow, such as at the ends of a pipe, are present.
- Laminar fluid flow in a circular pipe at the same direction.
-
- If N′R is less than about 1, flow around the object can be laminar, particularly if the object has a smooth shape.
- Depending on the surface, there can be a turbulent wake behind the object with some laminar flow over its surface.
- For an N′R between 10 and 10^6, the flow may be either laminar or turbulent and may oscillate between the two.
- (See . ) Laminar flow occurs mostly when the objects in the fluid are small, such as raindrops, pollen, and blood cells in plasma.
- Here the flow is laminar with N′R less than 1.
-
- It is possible to predict if flow will be laminar or turbulent.
- At low velocity, flow in a very smooth tube or around a smooth, streamlined object will be laminar.
- In fact, at intermediate velocities, flow may oscillate back and forth indefinitely between laminar and turbulent.
- In the spring, when the flow is faster, the flow may start off laminar but it is quickly separated from the leg and becomes turbulent.
- In the transition region, the flow can oscillate chaotically between laminar and turbulent flow.
-
- The air that flows through the lungs varies considerably in the properties of the flow of air.
- The air flow can either be turbulant, transitional or laminar based on the airway.
- Laminar flow involves an orderly and concentric distribution of layers of air particles and tends to occur in smaller airways, and has lower resistance.
- Transitional flow occurs in places that branch within smaller airways, in which the air flow becomes in between laminar and turbulent flow and has moderate resistance.
- Laminar flow (a) has orderly layers and low resistance.
-
- This is called laminar flow (also known as streamlined flow), and the velocity of the fluid's flow varies from close to zero near the pipe's boundaries to its greatest in the center.
- where F is the force required to move the plate (at constant speed), A is the area of the plate, $\frac {dv_x} {dy}$is the change in laminar velocity with respect to the perpendicular distance to the plate (y-direction).
- The term $\eta$ is called the viscosity, and it is a measure of a fluid's resistance to flow.
- When a fluid is less viscous, it flows more easily.
- Velocity of a fluid's layers, or lamina, during smooth flow.
-
- These factors affect fluid velocity depending on the nature of the fluid flow—particularly whether the flow is turbulent or laminar in nature.
- In the case of Laminar flow, however, fluid flow is much simpler and flow velocity can be accurately calculated using Poiseuille's Law.
- The magnitude of the fluid flow velocity is the fluid flow speed.
- This figure shows the relation between flow velocity and volumetric flow rate.
- Assess the significance of studying volumetric flow in addition to flow velocity
-
- UV light is commonly used to irradiate and sterilize laminar flow cabinets between uses.

- Free cash flow (FCF) is cash flow available for distribution among all the securities holders of an organization.
- In corporate finance, free cash flow (FCF) is cash flow available for distribution among all the security holders of an organization.
- There are four different methods for calculating free cash flows.
- Free cash flows = Cash flows from operations - Capital Expenditure ""
- Even profitable businesses may have negative cash flows.
-
- Observations in common include cytoplasmic displacement at the leading front and laminar removal of dorsally-accumulated debris toward trailing end.
-
- The flow rate of a liquid is how much liquid passes through an area in a given time.
- Volumetric flow rate can also be found with
- where Q is the flow rate, V is the Volume of fluid, and t is elapsed time.
- The equation of continuity works under the assumption that the flow in will equal the flow out.
- Since the fluid cannot be compressed, the amount of fluid which flows into a surface must equal the amount flowing out of the surface.
