A mechanical bar screen is to be used in an approach channel with a maximum approach velocity of 1 m/s in a channel with a width of 1.1m. The bars are 15mm thick, and the opening are 25mm wide. Draw a figure and determine the velocity between bars and the head loss when the screen is 40% clogged screens. Head loss coefficient for a clean and clogged bar screens - 0.65 and 0.83 respectively.

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.
