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.
Empirical equations used in a turbulent flow system?
there are many empirical constellations in turbulent flow depending upon the conditions like whether flow is internal or external, flow over a flat plate of pipe etc. so its better to refer a book on fluid mechanics.
What are examples of laminar and turbulent flow?
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.
Is Bernoulli equation applicable for unsteady flow?
The equation assumes steady state or laminar flow and hence cannot be used for turbulent flows.
Can a sheet flow be turbulent?
No...because.., whatever maybe the velocity u pump the liquid in sheet, the velocity would be same at all points (i think bernoulli's theorem)
What is turbulent flow?
Turbulent flow
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
Steady flow and non steady examples?
Steady flow: laminar flow over a sphere. Unsteady flow: turbulent flow over anything.
An irregular fluid flow is what?
Irregular Fluid Flow is called Turbulent Flow! I hope this helped! :D

What happen if Reynolds number is increased?
flow become turbulent. for ex. if Re <2000 flow is turbulent and if Re >4000 flow is turbulent and if RE is in between these values the flow is in transition region
Would you prefer turbulent flow or laminar flow for whitewater rafting?
As we know, whitewater rafting is in water, in which turbulent flow would be best in the case. Generally because the water will NOT be straight, and this activity is where the water flow is rather rough then smooth. Overall, turbulent flow is best used in this scenario.
How is turbulent flow different from laminar flow?
gago..

What are disadvantages and advantages of turbulent flow?
Advantage: objects in a turbulent flow experience less drag. Disadvantage: turbulent flows are unstable meaning velocity and pressures change rapidly. The objects in the flow have less stability. The flow also is more difficult to model then a laminar flow.
What is the equation for turbulent flow?
uc= Rn/pD
Which Objects reduce turbulent flow over water and air?
To reduce turbulent the key is to have streamlined shape of an object.
