A network of pipes is designed to drain excess water from a clayey soil with a permeability of 1 × 10^-7 m/s. Calculate the expected discharge if the hydraulic gradient is 0.3 and the cross-sectional area of the pipe is 0.5 m².
💡 Hint: Use the formula for discharge with the given values.
You are tasked with evaluating two different soil types for a highway project. Soil A has a permeability of 2 × 10^-5 m/s, while Soil B has 5 × 10^-6 m/s. How would this difference affect your design of drainage measures?
💡 Hint: Compare how permeability impacts drainage needs.
