Challenge Problems
Push your limits with advanced challenges
An engineer tests a soil sample with a constant head permeability apparatus and measures a head drop of 20 cm over a 1 m sample length. Calculate the permeability if the cross-sectional area of the sample is 0.1 m².
💡 Hint: Consider the formula and integration of variables involved to derive the permeability.
A falling head permeameter shows a decrease from 60 cm to 30 cm over 5 minutes. What does this indicate about the soil type and permeability?
💡 Hint: Analyze how quickly heads drop and apply the falling head calculation to draw conclusions.
