Challenge Problems
Push your limits with advanced challenges
A constant head permeameter shows a consistent head drop of 0.5 m over a 1 m length of coarse-grained soil with a cross-sectional area of 0.01 m². Calculate its permeability.
💡 Hint: Ensure you understand how to rearrange the equation to solve for k.
In a falling head test, the head drops from 1 m to 0.5 m in 10 minutes. Determine the hydraulic gradient and discuss how this would influence water flow in the given soil.
💡 Hint: Remember to use the correct values in your calculation after understanding how to derive the gradient.
