... the 37 Arnold Verruijt, Soil Mechanics : 6. DARCY’S LAW 41 for the no flow case. The equations (6. 6) can also be written as q x = − κ µ ( ∂p ∂x ), q y = − κ µ ( ∂p ∂y ), (6. 7) q z = − κ µ ( ∂p ∂z + ... + p γ w . (6. 8) If the volumetric weight γ w is constant it follows that ∂h ∂x = 1 γ w ( ∂p ∂x ), ∂h ∂y = 1 γ w ( ∂p ∂y ), (6. 9) ∂h ∂z = 1 γ w ( ∂p ∂z + γ w ). Arnold Verruijt, Soil...
