There are five (5) rain gauges dispersed throughout a watershed. During a storm event, four (4) of the rain gauges were working and collected the rainfall data given in the table below along with the annual average precipitation for each rain gauge. Determine the missing rainfall amount for the broken rain gauge using the quadrant (inverse distance) method, and the normal ratio.

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.
