Laminar flow can be defined by the help of Reynold's number that can be determined by conducting experiments. A Reynold number <=2000 indicates that the flow is laminar.
This question is its own answer. The flow patterns in laminar flow are laminar.
The Reynolds number, Re = VD/υ, can be used to measure the laminarity of flow. The smaller the Reynolds number, the more laminar the flow. Therefore, to achieve better laminar flow, V and D (velocity of fluid and diameter of pipe) should be small and υ, the kinematic viscosity of the fluid, should be large. Therefore, since pipe diameter and viscosity is fixed in this circumstance, the slower the velocity of the flow, the more laminar the flow. Open the faucet to a small degree and the flow will be laminar. Turn the facet open fully will (for some faucets) cause turbulent flow depending on the maximum velocity of water allowed by the faucet.
The equation assumes steady state or laminar flow and hence cannot be used for turbulent flows.
Coz poiseuille eq is for poiseuille flow, which is a laminar flow, not turbulent flow. And it also need to be a fully developed , pressure driven flow.
well laminar flow is required in aircraft and race cars .it is required sine we know that air transfers its momentum by sticking to the surface of the body . and thus creates pressure . now if the flow is turbulent it is not going to stick to the surface and going to destroy a considerable amount of momentum and not create sufficient amount of pressure that's why we need to have laminar flow in aircrafts and race cars. it is desired to be there in pipes in order to have a smooth flow.
difference between laminar air flow & reverse laminar air flow
This question is its own answer. The flow patterns in laminar flow are laminar.
A mixture of water and a mild detergent is commonly used to clean laminar flow hoods. Isopropyl alcohol can also be used to disinfect the surfaces. It's important to follow the manufacturer's recommendations for cleaning to maintain the integrity of the laminar flow.
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.
Laminar Flow - album - was created in 1979.
Increasing the radius of a pipe where laminar flow occurs typically leads to a decrease in the flow velocity needed to maintain laminar flow. This is because the flow rate is proportional to the radius to the power of four in laminar flow conditions. As a result, larger radii usually allow for higher flow rates while still maintaining laminar flow.

Laminar flow refers to smooth, orderly flow with predictable patterns, while turbulent flow is characterized by chaotic, irregular movement with swirling vortices and mixing. The transition from laminar to turbulent flow occurs when the flow speed or viscosity of the fluid increases, leading to the breakdown of laminar layers and the onset of turbulence.
Flow is Laminar.

Increasing the velocity of the fluid will cause a laminar flow to become turbulent.
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.
