Hemodynamics, Dr. D. Penney
Poiseuille equation
Written by Neumann and Hagenbach, 1858, based on the data of Poiseuille
Therefore:
F is proportional to Perfusion Pressure
F is proportional to 1 / Eta; inversely proportional to Eta.
F is proportional to r
^{4}
F is proportional 1 / length; inversely proportional to length.

r is most important factor physiologically in determining blood flow
P is second most important.
Applicability to the Eq. assumes:
Rigid conduit
Streamline flow
Newtonian fluid
