The laminar flow is characterized by Reynolds number which is Correct Answer Less than the critical value

Explanation:

The velocity at which the flow changes from the laminar to turbulent for the case of given fluid at a given temperature is known as critical velocity.

The laminar flow exists when the Reynolds number is less than the critical Reynold number. 

For flow through pipes

Laminar Flow: Re ≤ 2300

Transitional Flow: 2300 ≤ Re ≤ 4000

Turbulent Flow: Re ≥ 4000

For flow over flat plates

Laminar Flow: Re ≤ 1 × 105

Transitional Flow: 1 × 105 ≤ Re ≤ 5 × 105       

Turbulent Flow: Re ≥ 5 × 105
