Challenge Problems
Push your limits with challenges.
Question 1
Calculate the coefficient of permeability if a soil sample shows a drop in water level from 3.0 m to 1.5 m over 20 seconds. The length of the sample is 0.5 m and the cross-sectional area of the standpipe is 0.01 m². Assume the cross-sectional area of the sample is 0.02 m².
💡 Hint: Identify values for each variable in the formula to compute.
Question 2
Discuss how changes in soil saturation could affect the results of a falling head test. Provide a scenario illustrating your points.
💡 Hint: Consider both the chemical nature of the soil and timing of water entry.
