Poiseuilles equation

This is strictly applicable to steady (non-pulsatile) laminar (non-turbulent) flow of a Newtonian fluid (non-compressible fluid of uniform viscosity) within a straight, rigid, cylindrical tube. However, it can be used to derive the viscous energy losses associated with the flow of blood.

. pressure difference x radius4

viscosity x length

Poiseuille's formula is:

fil pressure difference between the ends of a tube x radius'

8 x length of tube x viscosity

Where Q — volume flow per unit time

AP = pressure head r — radius I — length of tube Z — viscosity of the fluid The circulatory system uses blood pressure and radius of vessels for the short-term control of blood flow rate.
