Properties of Fluids

The term fluid represents a type of substance that can easily change its shape under any external pressure/force and can flow. Fluids can acquire any shape in which it is stored and can resist normal stresses but cannot resist shear stress in rest condition. Whenever external shear stress is applied to fluids, it starts to flow. The fluids may be liquid or gas. Example- water, air, etc.

When a fluid flows over a surface, the shear stresS I (N/m) at the surface is given by the expression du dy surface where u is the viscosity (N-s/m), u is the velocity parallel to the surface (m/s), and y is the distance normal to the surface (cm). Measurements of the velocity of an air stream flowing above a surface are made with an LDV (laser-Doppler-Velocimeter). The values given below were obtained. y u y и 0.0 0.00 2.0 88.89 1.0 55.56 3.0 100.00 At the local temperature, u = 0.00024 N-s/m.

Atmospheric pressure can be reported in several ways. At sea level the average atmospheric pressure is 15 lbs/sq in, or 101.3 kPa, or 760 mm Hg, or 1 atmosphere. Since all of these are equal, you can easily convert from one to the other. For example, if your tire pressure is 32.0 lbs/square inch, you can determine the kilopascals in the following manner: 32.0 lb/sq in X 101.3 kPa / 15 lbs/sq in = 216 kPa.
