Variables Used
Difference in Pressure - (Measured in Pascal) - Difference in Pressure is the difference between the pressures.
Viscosity of Blood - (Measured in Pascal Second) - 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.
Length of the Capillary Tube - (Measured in Meter) - 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.
Blood Flow - (Measured in Cubic Meter per Second) - The blood Flow involves a cyclic series of steps that move blood trough the heart and to the lungs to be oxygenated.
Radius of Artery - (Measured in Meter) - The radius of artery is the radius of the blood vessel involved in circulatory system.
STEP 1: Convert Input(s) to Base Unit

## 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.
