If flow changes from laminar to transition implies lower critical and from the transition to turbulent implies higher critical.
Re 2800 means transition flow to laminar ie upper critical.
Re 2800 means transition flow to laminar ie upper critical.

The flow at which laminar flow stops is called lower critical velocity (RN 2000).
The flow at which turbulent flow starts is called higher critical velocity (RN 2800).
The flow at which turbulent flow starts is called higher critical velocity (RN 2800).

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.

Low critical velocity is laminar flow.
High critical velocity is turbulent flow.
Here they give 2800 is laminar flow so, it should be a low critical velocity.
High critical velocity is turbulent flow.
Here they give 2800 is laminar flow so, it should be a low critical velocity.

So Mach number depends on the speed of sound waves and Reynolds number used to measure type of flow and Q asked type of velocity not a flow.

Flow in pipes Re <2000 - laminar.
Flow in pipes Re 2000-4000 - transition.
Flow in pipes Re >4000 - turbulent.
Flow in pipes Re 2000-4000 - transition.
Flow in pipes Re >4000 - turbulent.

Higher critical velocity-at which flow changes from transition state to turbulent.

If re>2000, the velocity is called critical or turbulent flow.
