Laminar flow is dependent ona) Critical velocityb) Viscosityc) Constant velocityd) Critical closing pressure
Correct Answer: ab
Description: The flow of blood (Laminar or turbulent) depends on
- Fluid density (S)
- Tube diameter (D)
- Velocity of fluid (V)
- Viscosity of fluid (n)
This can be expressed by Reynold’s number (R) = SDV/n
Normal flow is laminar. But if the velocity crosses a critical limit (Critical velocity) flow becomes turbulent. If R>2000, flow is turbulent.
