Following are the basic fluid properties
I. Density – Density is defined as ratio of mass and volume of fluid.
Density is denoted by ‘ρ’
Formula of density = Mass/Volume
Unit of density – kg/m3
II. Viscosity – Viscosity is defined as property of fluid that is resist to shear force on it. Because of viscosity fluid offers resistance to one layer over another adjacent layer.
Viscosity denoted by ‘µ’.
Unit of viscosity is ‘m2/s’.
III. Temperature – Temperature is defined as property of fluid that is define the degree of hotness or coldness fluid.
Temperature is denoted by ‘T’.
Unit of temperature is ‘°C’.
IV. Pressure – Pressure is the ratio of force and unit area of fluid.
Pressure is denoted by ‘P’.
Formula of force, P = F/A
Unit of pressure is ‘N/m2’
V. Specific volume – Specific volume is ratio of volume of fluid and occupied per unit mass.
Specific volume denoted by ‘v’
Formula of Specific volume (v) = V/m
Unit of Specific volume is ‘m3/kg’
VI. Specific weight – Specific weight is defined as weight possessed by per unit volume.
Specific weight denoted by ‘w’
Formula of specific weight (w) = W/V
Unit of specific weight is ‘N/m3’
VII. Specific gravity – Specific gravity is defined as ratio of specific weight of given fluid and specific weight of standard fluid.
Specific gravity denoted by ‘S’
Formula of specific gravity (S) = Specific weight of given fluid/Specific weight of standard fluid
It has no unit.
