\

Poiseuille $\"\"$ s Law :

\

The rate of flow is $\"\"$ .

\

Where $\"\"$ is the pressure loss,

\

$\"\"$ is the length of pipe,

\

$\"\"$ is the dynamic viscosity,

\

$\"\"$ is the radius.

\

$\"\"$

\

Show that, $\"\"$ and $\"\"$ are related by the equation $\"\"$ .

\

Where $\"\"$ and $\"\"$ are normal values of the radius and pressure in an artery.

\

$\"\"$ and $\"\"$ are the constricted values.

\

Consider $\"\"$ .

\

Since the flow $\"\"$ to remain constant, $\"\"$ .

\

$\"\"$

\

$\"\"$

\

Since the radius is $\"\"$ it $\"\"$ s formel value, consider $\"\"$ .

\

$\"\"$ and $\"\"$ are related by the equation $\"\"$ .

\

Substitute $\"\"$ in above equation.

\

$\"\"$

\

Therefore, the pressure is more than tripled.

$\"\"$

\

$\"\"$ and $\"\"$ are related by the equation $\"\"$ .

\

The pressure is more than tripled.
