Variables Used
Viscosity of Blood - Viscosity of Blood is a measure of the resistance of blood to flow. It can also be described as the thickness and stickiness of blood. (Measured in Centipoise)
Length of the Capillary Tube - Length of the Capillary Tube is the length of tube in which a liquid flows up into the tubes against gravity in a process called capillary action. (Measured in Meter)
Blood Flow - The blood Flow involves a cyclic series of steps that move blood trough the heart and to the lungs to be oxygenated. (Measured in Milliliter per Sec)
Radius - Radius is a radial line from the focus to any point of a curve. (Measured in Meter)

ΔP = (8*μ*Lc*Q)/(pi*(r^4))

## What is Hagen–Poiseuille equation?

It is a physical law that gives the pressure drop in an incompressible and Newtonian fluid in laminar flow flowing through a long cylindrical pipe of constant cross section. It can be successfully applied to air flow in lung alveoli, or the flow through a drinking straw or through a hypodermic needle.
