Which of the following increases turbulence in blood flow
Reynolds number less than 2000
Decrease in velocity of blood
Decrease in density of blood
Increase in diameter of blood vessel
The flow of blood (Laminar or turbulent) depends on
-        Fluid density (S)
-        Tube diameter (D)
-        The velocity of the fluid (V)
-        The 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.
