What is relation between Reynold number & mach number?

Shobhit kumar said:   1 decade ago
When mech number <1 the flow is sub sonic.

When mech number =1 the flow is sonic.

When mech number lies between 1 to 6 the flow is supersonic.

When mech number >6 the flow is hyper-sonic.

Ankith sub sonic & super sonic is measured with the help of Mach number.

@Girish for turbulent flow Re>4000.

Girish Changavi said:   1 decade ago
If Re >2000, tts laminar flow.

If Re < 4000 its turbulent flow.

If between 2000 to 4000 its transition flow.

Here Re is 2800 so its higher critical velocity.

When is it call sonic & super sonic?

Gowtham said:   1 decade ago
If re>2000, the velocity is called critical or turbulent flow.
