Laminar Airflow describes the flow around an object such that the air stays "attached" to the surface. At higher airspeeds, the air become detached and turbulent. Thus a laminar flow chamber is one where airfoils or model airplanes are tested at low airspeeds and especially airspeeds less than Mach 1.0.

What is the red colour fluid which is present in laminar air flow?
aminar Flows Laminar air flows can maintain a working area devoid of contaminants. Many medical and research laboratories require sterile working environments in order to carry out specialised work. Laminar Flow Cabinets can provide the solution.Why Laminar Flow Cabinets? Laminar Flow Cabinets create particle-free working environments by projecting air through a filtration system and exhausting it across a work surface in a laminar or uni-directional air stream. They provide an excellent clean air environment for a number of laboratory requirements.Uses Laminar Flow Cabinets are suitable for a variety of applications and especially where an individual clean air environment is required for smaller items, e.g. particle sensitive electronic devices. In the laboratory, Laminar Flow Cabinets are commonly used for specialised work. Laminar Flow Cabinets can be tailor made to the specific requirements of the laboratory and are also ideal for general lab work, especially in the medical, pharmaceutical, electronic and industrial sectors. How They Are Made Laminar Flow Cabinets, or laminar air flow cabinets as they are also known, are normally made of stainless steel with no gaps or joints thereby preventing the build-up of bacteria from collecting anywhere in the working zone. Laminar Flow Cabinets are also known as clean benches because the air for the working environment is thoroughly cleaned by the precision filtration process.How They Work The process of laminar air flow can be described as airflow where an entire body of air flows with steady, uniform velocity. Laminar Flow Cabinets work by the use of in-flow laminar air drawn through one or more HEPA filters, designed to create a particle-free working environment and provide product protection. Air is taken through a filtration system and then exhausted across the work surface as part of the laminar flows process. Commonly, the filtration system comprises of a pre-filter and a HEPA filter. The Laminar Flow Cabinet is enclosed on the sides and constant positive air pressure is maintained to prevent the intrusion of contaminated room air.
What are the basic differences between laminar air flow and biosafety hood?
Do you know the difference between a laminar flow hood and a biological safety cabinet? Laminar Flow Hoods * provide product protection only and must not be used when working with any form of biohazard or chemical hazard * any potentially infectious aerosol that is created will lead to exposure of the operator and the environment * horizontal-flow clean-air bench used for cell cultures can expose the researcher to aerosols of allergenic or infectious materials. * vertical-flow clean-air bench also blows air out into the roomBiological Safety Cabinets * provide personnel and environmental protection and commonly product protection * infectious agents must be used in a biological safety cabinet NOT a laminar flow hood
What are the factors that affect the air movement?
reynolds number less than 2000 is laminar flow and reynolds number greater than 4000 is a turbulent flow
What is the underlying mechanism of a laminar flow hood in microbiology?
The underlying mechanism of a laminar flow hood in any application, including microbiology is that a roughly non-turbulent flow of air is more effective at preventing cross contamination of materials in the hood and having that air go through a high efficiency filter first is effective in preventing contamination by microbes and other items from outside the hood.
Can we use the UV light in laminar air flow to see DNA bands in agarose gels stained with Ethidium bromide?
One cannot use the UV light installed in a laminar air flow hood to visualize DNA in an agarose gel. You will have to use an instrument called a UV transillumunator, which illuminates the gel from below to see the stained DNA.
What is the Role of laminar air flow chamber in sterilization of mushroom?
The laminar air flow chamber is a way to provide a sterile work area. This lowers the possibility of contamination while working with your cultures or fungi.
Difference between laminar air flow and reverse laminar aire flow?
difference between laminar air flow & reverse laminar air flow
Why is no obstruction important for air flow techniques?
The laminar flow hood depends on the laminar air flow to sweep away pathogens from the hood. If there is obstruction, the laminar air flow pattern will be disrupted. The laminar air flow will then change to turbulent air flow.
Who invented laminar air flow?
Bernoulli was the first guy to study it some 250 years back - laminar fluid flow that is.
What are the differences between horizontal and vertical laminar flow hoods?
In a horizontal laminar flow hood, the laminar air flows towards the outside (i.e. towards the worker). There is hence no protection to the worker and it is not suitable for cytotoxic drug preparation. In a vertical laminar flow hood, the laminar air flows downwards from the top, providing more protection for the workers. Vertical laminar flow hoods are hence suitable for preparing cytotoxic drugs.

What are flow patterns around a stationary object in laminar flow?
This question is its own answer. The flow patterns in laminar flow are laminar.
Where can someone purchase a Laminar flow hood?
Laminar flow hoods can be found through ebay's website. Companies NuAire, Terra Universal, and Air Clean Systems all offer their own laminar flow hoods (also called laminar flow closets and tissue culture hoods) on their official websites.
Which is used to measure the pressure in laminar air flow?
15lb pressure
What is turbulent vs laminar flow?
An air plane wing or anything that reduces drag like an arrow,dart, or even fish. Other examples could be the fins of dolphins, blood through arteries, water in a tube. Just remember that laminar flow is flow in which the fluid flows smoothly without much resistance. The fluid pretty much travels in straight or almost straight lines.
When was Laminar Flow - album - created?
Laminar Flow - album - was created in 1979.
What is an air chamber?
An air chamber is a chamber in a hydraulic system in which air is compressed to regulate the flow of a fluid.
