When the density is a constant, then Equation 9.2(12) is reduced to

dx dy dz

This equation is called the equation of continuity.

Fundamental Equations

Darcy's law and the continuity equation provide four equations for the four unknowns. Substituting Darcy's law Equation 9.2(9) into the equation of continuity Equation 9.2(13) yields
