2. The figure below shows a vertical column of length L-100 cm filled with a homogeneous sand. The piezometric head at the inflow and outflow ends of the column) are at elevations h₁ and 2. respectively, above some datum level. The steady state, uniform flow rate through the column is Q. 115 Sand Screen : Screen - (a) For h₁ 115 cm and h₂ 15 cm, draw the piezometric head, h, and pressure head, . distributions along the column. (b) Repeat part (a) for h₁ (c) Repeat part (a) for h₁ 125 cm and h₂-15 cm. 115 cm and h₂ - 25 cm. (d) Briefly discuss the difference between cases (a), (b), and (c). (e) Will the h and distribution change if the hydraulic conductivity and/or the porosity are doubled in Cases (8), b) and (e)?
