Linear Flow, Incompressible Liquid 1-D Linear Flow System Assumptions • steady state flow • incompressible fluid, q(0 s L) = constant •d Φ includes effect of dZ/ds (change in elevation) •A ( 0 s L) = constant • Darcy flow (Darcy’s Law is valid) • k = constant (non-reactive fluid) • single phase (S=1) • isothermal (constant μ ) L q A 1 2
Linear Flow, Incompressible Liquid • Darcy’s Law: •q 1 2 > 0, if Φ 1 > Φ 2 • Use of flow potential, Φ , valid for horizontal, vertical or inclined flow L q A 1 2 = = ds d Φ μ k A q v s d Φ μ kA ds q = Φ Φ = 2 1 d Φ μ kA ds q L 0 () 2 1 L μ A k q Φ Φ =
