Laminar flow is dependent ona) Critical velocityb) Viscosityc) Constant velocityd) Critical closing pressure

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.
