Which of the following increases turbulence in blood flow
Correct Answer: Increase in diameter of blood vessel
Description: 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.
