Challenge Problems

Push your limits with challenges.

Question 1

In a lab, a soil sample achieved a head drop from 80 cm to 30 cm over 45 seconds with a standpipe area of 5 cm². Calculate its permeability assuming the sample area is 20 cm².

💡 Hint: Remember to convert your head values to meters for accurate calculations.

Question 2

Discuss how higher clay content in a soil influences its permeability as measured by Falling Head Flow and the implications this has for construction projects.

💡 Hint: Consider properties of clay and how they differ from coarse-grained soils.
