Moist unit weight
In fluid mechanics, specific weight represents the force exerted by gravity on a unit volume of a fluid. Specific weight can be used as a characteristic
Charles’ law is an experimental gas law which describes how gases tend to expand when heated. When the pressure on a sample of a dry gas is held
Reduced specific volume
In thermodynamicsIn thermodynamics, the reduced properties of a fluid are a set of state variables normalized by the fluid’s state properties at its
Atomic packing factor
In crystallography, atomic packing factor (APF), packing efficiency or packing fraction is the fraction of volume in a crystal
The density of a material is defined as its mass per unit volume. For a pure substance the density has the same numerical value as its mass concentration.
