BASIC CONCEPTS AND PROPERTIES
FLUID – that deforms continuously subjected to tangential or shear stress.
Solid can resist tangential stress under static conditions, but fluid can do it under dynamic conditions.
Fluid mechanics deals with the behaviour of the fluid at statics (at rest), kinematics (no pressure) and
dynamics (with pressure forces).
PROPERTIES OF FLUIDS
Density (ρ): mass of fluid to its volume (kg/m3). Ex: Water - 1000kg/m3
Specific density(w): Weight of fluid to its volume = ρ×g Ex: 9810N/m3.
Specific gravity(S): Weight density of liquid to water
Ex: Mercury = 13.6
Viscosity: resistance to the movement of one layer of fluid over adjacent layer of the fluid.
