It is important to know how to pick your logistic equipment to minimize cost that you pay for material or finished good flow. There are different type of logistics equipment and methodology available in the market. But you must know which one is best for you.
Before you pick your logistics method, firstly you need to know your material better than anything. First course is density. Calculate your material's density first.
The density, or more precisely, the volumetric mass density, of a substance is its mass per unit volume. The symbol most often used for density is ρ (the lower case Greek letter rho), although the Latin letter D can also be used. Mathematically, density is defined as mass divided by volume:where ρ is the density, m is the mass, and V is the volume. In some cases (for instance, in the United States oil and gas industry), density is loosely defined as its weight per unit volume, although this is scientifically inaccurate – this quantity is more specifically called specific weight. Please see wikipedia
Here you can find three different part dimensions and shipping unit (SU) weight. Density is a formula of weight divided by volume of the part.
