Question

Problem 8.2: The figure below shows an experimental siphon apparatus. Assume the column is of constant cross-sectional area, is packed with sand, and is fully saturated. (This problem requires carefully considered application of Darcy's Law.) a) Calculate the hydraulic and pressure heads at points A through I (fill in the table provided below). b) In what direction is water flowing through the siphon? Point p/pg (cm) z (cm) h(cm) 10 cm Glass tubing filled with sand. fully saturated CO C OS-Rectional area Reserva 20 cm
