Laboratory tests on a 25-mm-thick clay specimen drained at the top and bot- tom show that 50% consolidation takes place in 8.5 min. a. How long will it take for a similar clay layer in the field, 3.2 m thick and drained at the top only, to undergo 50% consolidation? b. Find the time required for the clay layer in the field described in part (a) to reach 65% consolidation.

Unit Conversion

Standard units are also called SI units. SI units are used for measuring a physical quantity satisfying certain conditions. There are two types of units: fundamental units and derived units. Fundamental units are physical quantities that are independent, that is, they do not depend on other quantities like mass, length, or time. There are plenty of quantities in our lives which need to be measured and compared. Measuring is the comparison of a particular physical quantity with its reference value. A unit is a measure of a fixed physical quantity. A physical quantity is the product of a unit and the numerical value we need to compare with.
