Blood Speed in an Arteriole

  • Thread starter eagles12
  • Start date
1. Homework Statement

A typical Arteriole has a diameter of .030 mm and carries blood at the rate of 5.5* 10^-6 cm^3/s. What is the speed of the blood in an arteriole?

2. Homework Equations

s=P/vρ

3. The Attempt at a Solution

Blood is made of mostly water, so I used the same ρ as water (ρ=1000), and multiplied by the velocity given. I have the diameter, but I am not sure what do do with it or how to find the pressure.

Volumetric flow is given by:

Q=A*V and has the units of volume per unit time. A is area, V is velocity

So, determine the velocity from the above equation.
 
I already have velocity, I am looking for speed

Speed is the magnitude of velocity. Velocity is a vector entity. It has both magnitude and direction. Speed is only the magnitude of velocity.
