There is no relation between mach number and Reynolds number,
Mach number is used to measure the speed of sound waves and Reynolds number is used to measure the type of the flow.
Mach number is the ratio of flow velocity to the speed of light.

What is relation between Reynold number & mach number?

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.
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.

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.
If Re < 4000 its turbulent flow.
If between 2000 to 4000 its transition flow.
Here Re is 2800 so its higher critical velocity.
