Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

A soil sample shows a constant flow of water at a rate of 0.5 L/min with a cross-sectional area of 0.1 m² and a head drop of 2 m over a 1 m length. Calculate its permeability.

💡 Hint: Pay attention to the units and conversions.

Challenge 2 Hard

In a falling head test, water height drops from 80 cm to 30 cm in 15 minutes. Calculate permeability if the standpipe area is 0.05 m² and cross-section of the soil sample is 0.1 m².

💡 Hint: Keep track of the drop in height and associated time.
