Reynolds number is a dimensionless formula that is used to differentiate laminar flow from turbulent flow. It is denoted by Re.
Open channel Flow:
Re < 500 → Laminar
Re > 2000 → turbulent
500 < Re < 2000 → transition
Additional Information
Pipe flow:
Re < 2000 → Laminar
Re > 4000 → turbulent
2000 < Re > 4000 → transition
Parallel plates:
Re < 1000 → Laminar
Re > 2000 → turbulent
1000 < Re < 2000 → transition
For flow through soil:
Re < 1 → Laminar
1< Re < 2 → transition
Re > 2 → turbulentLast updated on May 28, 2025
