Fluid Properties

Mass Density:

It is the mass of the fluid per unit volume. Its unit is kg per cubic meter.

ρ = m / V  

ρ ( r h o ) {\displaystyle \rho (rho)}

Specific Weight:

It is the weight per unit volume of the fluid.

It is the volume occupied by the unit mass of the fluid.

Specific gravity:

It is the ratio of specific weight of fluid to specific weight of standard fluid.

It has a dimensionless unit

Standard fluids are generally water and air

Compressibility:

Compressibility is the reciprocal of bulk modulus of rigidity.

Compressibility generally shows the ability of molecules in a fluid to be compacted or compressed and their ability  to return its  their original density

Kinematic viscosity:

Kinematic viscosity is the ratio between Dynamic viscosity and density.

Surface tension:

Energy exerted on a surface of a liquid bye the downward force of the molecule is known as the Surface Tension.

Capillarity:

Capillarity is the phenomenon in which when we insert a small tube in a liquid vessel, the phenomenon of rise or fall of a liquid level in tube is called capillarity.

Capillary rise- dipped in water

Capillary  fall-dipped in mercury.
