How is water with 120 µm-diameter particles clarified using a settling tank that is 32 m long, 2.1 m wide, and 1.6 m deep? The dynamic viscosity of water is 1.3 x 10-2 g/cm.sec. and the density of the particles is 2.5 g/cm3. What flow rate can be permitted at its maximum to ensure that all the particles land in the tank?

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.
