A permeameter is used to measure the hydraulic conductivity of a porous medium. The permeameter is perfectly round in cross section, with a diameter of 40.0 mm. The following parameters are measured: 21 = 200.0 mm, 22 = 150.0 mm, P1/pg = 280.0 mm, P/pg = 200.0 mm, with L = 100.0 mm, and a discharge at the...
