A differential equation (de) is an equation involving a function and its deriva-tives. Differential equations are called partial differential equations (pde) or or-dinary differential equations (ode) according to whether or not they contain partial derivatives. The order of a differential equation is the highest order derivative occurring.

Alternative equations are the Forchheimer equation, for high velocity flow: n − ∂P ∂x = u µ k + βu, where n was proposed by Muscat to be 2, and the Brinkman equation, which applies to both porous and non-porous flow: − ∂P ∂x = u µ k −µ ∂2u ∂x2. Brinkman's equation reverts to Darcy's equation for flow in porous media, since ...
