In nonideal fluid dynamics, the Hagen–Poiseuille equation, also known as the Hagen–Poiseuille law, Poiseuille law or Poiseuille equation, 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.

Explanation:
Linear Regression The Poissuile equation for the flow rate (Q, m^3/s) through a small diameter capillary tube is: Q = pi R^4/8 eta L delta P Where delta P= pressure drop in Pa, R =tube radius (m), L =tube length (m) and eta = the viscosity of fluid.
