Challenge Problems
Push your limits with advanced challenges
A constant head permeameter measures water flow at 3 liters/min through a 1 meter soil sample with a head of 2 meters. Calculate the permeability.
💡 Hint: Keep the units consistent for accurate calculations.
In a falling head test, the head drops from 0.8 m to 0.3 m over 15 minutes. If the test setup gives an effective area of standpipe of 0.005 m^2, determine the permeability.
💡 Hint: Focus on the logarithmic relationship between the heads for accurate results.
