Laboratory test on a 35 mm thick clay specimen drained just at the top show that 60% consolidation takes place 9.5 minutes. a) How long will it take for a similar clay layer in the field, 3,6 m thick, but drained at both the top and bottom, to undergo 60% consolidation? b) Find the time required for the clay layer in the field as described in part (a) above to reach 70% 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.
