Properties of Fluids
The fluid is any substance that flows since its particles are not tightly attached to one another. This involves liquids, gases and even few materials that are generally considered solids, like glass. Fundamentally, fluids are materials that have no replicating crystalline structure.
The properties are mainly discussed in Thermodynamics. These involved pressure, temperature, mass, specific volume and density. The temperature was stated as the associative measure of how hot or cold a material is. It can be employed to forecast the direction which heat will be transferred. The pressure was stated as the force per unit area. General units for pressure are pounds force per square inch (or psi). Mass was stated as the quantity of matter enclosed in a body and is to be differentiated from weight that is measured by the pull of gravity lying on a body. The specific volume of a substance is the volume per unit mass of the substance. Usual units are ft3/lbm. The density, on the other hand, is the mass of a substance per unit volume. Usual units are lbm/ft3. The density and specific volume are the inverse of one another. Both specific volume and density is dependent on the temperature and fairly on the pressure of the fluid. Since the temperature of the fluid rises, the density reduces and the specific volume rises. As liquids are considered incompressible, a rise in pressure will outcome in no change in density or specific volume of the liquid. In realism, liquids can be slightly compressed at high pressures, resultant in a slight rise in density and a slight reduce in specific volume of the liquid.
