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
Atomic packing factor
In crystallography, atomic packing factor (APF), packing efficiency or packing fraction is the fraction of volume in a crystal
Piston stroke (displacement )
Almost all reciprocating engines use cranks (with connecting rods) to transform the back-and-forth motion of the pistons into rotary motion. The cranks are
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.
Saturated 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
