Density and mass per unit volume convert

Fluid density is constantly present in the equations of fluid mechanics.

The mass per unit volume is the ratio of the mass by its volume the unit used is Kg/m3

For purists, I met some, I specify that the density of a liquid is the ratio of the mass per unit volume of the material on the water mass per unit volume. (for a gas, the ratio will be taken with the mass per unit volume of the air) This gives us a dimensionless number, without unity, which is the density of the material

Exemple: the water mass per unit volume is 1000 Kg/m3

the mass per unit volume of the oil is 800 Kg/m3

the density of the oil is=800/1000= 0.8

Density of water=1000/1000= 1

With Mecaflux standard

The density of the liquid or gas is provided in the fluid editor:

The editor gives density , mass per unit volume of the fluid selected depending on the temperature but also its viscosity and saturation vapor pressure.
