Question

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: z, = 200.0 mm, z = 150.0 mm, P,/g = 280.0 mm, P/g = 200.0 mm, with L 100.0 mm, and a discharge at the lower end of the column Q = 250.0 mm/min.
