Based on Reynolds number when is the flow of fluid is laminar, turbulent or in transient state ?

Give us the range of the value of Reynolds number for each state.

1. You can answer this question

2. You can like the best answer

3. You can share the question.....

if the Re<2000 then laminar flow

,,,,,,, Re>4000 then turbulent flow

,,,,,,,,,Re b/w the 2000-4000 then changing laminar to turbulent. (transition state)

the flow is laminar when Re<2300

the flwo is transient when 2300<Re<4000

the flow is turbulent when 4000<Re

re<2300 laminar

re>4000 turbulent

b/t 2300 to 4000 transient

the above answers are valid when the fluid flow occurs inside a pipe and its value varies based on type of fluid and flow conditions.

If Re>1000 it is laminar flow,Re>2000 it is turbulant flow & Re is in between 1000-2000 it is tranisition flow

It depends on the where the flow is taking place

1.IN CASE OF FLAT PLAT

Laminar flow when Re<5,00,000

Turblent flow when Re>10^(7)

2.IN CASE OF PIPE LINE

Laminar Re<2000

Transient 2000

Turbulent Re>4000

It depends on where the flow is taking place. Subrahmanyam have said it all

When Re is less than 2300 is laminar flow ..
Greater  than 4000 is turbulent.
App. is mixiture of laminar amd turbulent (turbulence at the center of the i.e pipe and laminar flow near the edges)as transient state and Re is between 2300 &4000
