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.

∙ 11y agoWhen the faucet valve is in a low position the water flow coming out runs in a smooth stream with no air bubbles or ripples as in laminar flow. As the valve is opened and the flow increases the water gets more disturbed with waves and ripples and bubbles as in non-lamiar turbulent flow.

What are examples of turbulent flow?
Smoke rising from a flame. At first the smoke rises with laminar flow before becoming turbulent just a few centimetres above the source.
Why poiseuille equation not applied to turbulent flow?
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.
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.
What can be used to define laminar flow?
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.
Is Bernoulli equation applicable for unsteady flow?
The equation assumes steady state or laminar flow and hence cannot be used for turbulent flows.
How is turbulent flow different from laminar flow?
gago..
Steady flow and non steady examples?
Steady flow: laminar flow over a sphere. Unsteady flow: turbulent flow over anything.

What is the translation from laminar to turbulent flow?
laminar =viscosity drops intertaily motion Turbulent = intertia dominates motion.
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.
What is the difference between laminar and turbulent flame patterns?
In laminar flow, easy to define the burning velocity, independent of the measuring apparatus within reasonable limits whereas not possible to turbulent flow.
Is flow in a Venturi tube laminar or turbulent?
In laminar flow, air resistance is proportional to velocity of the body whereas in turbulent flow, air resistance is proportional to (velocity)2.
Why you determine reynold number in fluid mechanics?
Reynolds number tells you what the flow is doing. A Reynolds number of 0-2000 is laminar flow 2000-4000 is the transition (where both laminar and turbulent flow is possible) 4000+ is fully turbulent flow
Why poiseuille equation not applied to turbulent flow?
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.
Would you prefer turbulent flow or laminar flow around a racing bicycleWhich would you like for whitewater rafting?
You want laminar around a bicycle for less resistance, but turbulent in rafting so that you get all of the white water
What are some examples of turbulent flow?
a block, Ping Pong ball or golf ball, kite, or simply running in the shallow pool. There are alot of things that have turbulent flow..... ping pong balls do not have turbulent flow nor does golf balls it has laminar flow things that have turbulent flow would be a bus, a hand out the window in a y axis or just a simple building or sky scrapper basically anything with a flat surface has turbulent flow
