AN ALTERNATIVE FORM OF THE DARCY EQUATION

ABSTRACT
This study presents an alternative form of the Darcy equation. This alternative form will be presented with the use of Bejan number (Be) in the Left Hand Side (LHS) of the equation. The main advantage in this alternative form of the Darcy equation is presenting both the Left Hand Side (LHS) and the Right Hand Side (RHS) as dimensionless quantities. For instance, this is similar to the relation of Fanning friction factor with Reynolds number for Hagen-Poiseuille flow (fully developed laminar flow in a circular pipe).
