Notes

Please find out the units of the following properties and add equations in the space.
Pressure (P)
Pressure is the intensity of force due to molecular bombardment.
Force per unit area.
Units:-
Temperature (T)
In gases, molecules move randomly the amplitude of the
motion being about 76 x 10-9 m in normal conditions, to
tens of millimeters at very low pressure.
The energy of the molecules is sensed as temperature.
Units:-
Volume (V)
Volume is the measure of space that the fluid takes up.
Units:-
Specific volume (v)
The specific volume is the volume of unit mass of fluid
and is the reciprocal of density.
Units:-
Density (, ‘Rho’)
Density is the mass per unit volume of the fluid.
Units:-
Specific weight (, ‘Omega’)
This is the weight per unit volume for the fluid, and is
related to density by
[Equation missing here]
where g is the local acceleration due to gravity.
Units:-
Relative density (, Gamma)
This is defined, for a liquid, as the density of the liquid,
divided by the density of water at 4C. For a gas it is the
density of the gas, divided by the density of air under
standard sea level conditions (a temperature of 15C and
a pressure of 1.013 x 105N/m2).
Units:-
(Dynamic) Viscosity (, ‘Mu’)
Viscosity is a property of the fluid which is a measure of
its resistance to a force causing one layer of the fluid to
move over another i.e. shear. In this way, liquids such as
tar, treacle have a higher viscosity than water and petrol.
Units:-
Kinematic viscosity (, ‘Nu’)
Kinematic viscosity is the ratio of the viscosity to the
density this ratio is a fluid property used when comparing
the magnitude of viscous forces to inertia forces.
