Q4/ The pressure drop in a certain length of 0.3 m horizontal waterline is 68.95 kPa when the mean velocity is 4.5 m/s and the water temperature 20°C. If a 1:6 model of this pipeline using air as the working fluid is to produce a pressure drop of 55.2 kPa in the corresponding length when the mean velocity is 30 m/s, calculate the air pressure and temperature required for dynamic similarity between model and prototype.

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.
