Solids analysis is one of the important parameters for assessing water quality. Use the following data for calculating total solids (TS), volatile solids (VS), dissolved solids (DS), total suspended solids (TSS), and total volatile suspended solids (TVSS) all in mg/l. A sample volume of 150 ml was used in performing all solids analysis: Tare mass of evaporating dish = 24.3520 g Mass of evaporating dish plus residue after evaporation @ 105 °C = 24.3970g Mass of evaporating dish plus residue after ignition @ 550 °C = 24.3850g Mass of Whatman filter and tare = 1.5103g Mass of Whatman filter and tare after drying @ 105 °C = 1.5439g Residue on Whatman filter and tare after ignition @ 550 °C = 1.5199g

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.
