What does the tangent PQ represent in a consolidation graph?
💡 Hint: Think about how a tangent relates to slopes on a curve.
True or False: The more extended the drainage path, the shorter the time for consolidation.
💡 Hint: Consider the implication of distance on drainage time.

Challenge Problems
Push your limits with advanced challenges
A soil sample shows a plotted tangent at an initial pressure of 50 kPa and a slope of 0.2. If the drainage path is 5 m, calculate the expected consolidation time.
💡 Hint: Remember to square the drainage path and relate it to the established slope.
Considering a curve with two distinct sections, how can you mathematically express the relationship between the rates of consolidation in each section?
💡 Hint: Think en route about how pressure increments can reflect different characteristics across sections.
