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.

The diameter of a pipe changes gradually from 75 mm at a point A, 6 m
above datum, to 150 mm at B, 3 m above datum. The pressure at A is
103 kPa and the velocity of flow is 3.6 m/s. Neglecting losses, with the
aid of a neat sketch, determine the pressure at B.
