In an Oedometer test, a clay specimen with initial thickness 25 mm attained 90% consolidation in 12 minutes. The clay stratum in the field from which the specimen was obtained has a thickness of 6m and is sandwiched between two sand layers. A structure constructed on this clay will experience an ultimate settlement of 200 mm. Estimate the settlement at the end of 100 days after construction

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.
