Which is the correct formula for calculating filler density?
Thread Content
Metal plate corrugated structured packing is the most commonly used type of structured packing. Its cost and price need to be estimated both during manufacturing and when purchasing it. Therefore, it is very important to estimate its material weight. What is the material weight of 1 cubic meter of metal plate corrugated structured packing? Which of the following two calculation formulas do you think is correct? A: Specific surface area of the packing * Thickness of the packing plates * Density of the material B: (Specific surface area of the packing / 2) * Thickness of the packing plates * Density of the material (Weight = Volume of the material * Density = Area of the material * Thickness of the material * Density) There is a type of packing designated as 350; the thickness of its thin plates is 0.17 mm, and the density of the material is 7930 Kg/m3. What is its volumetric density? Which of the following options is correct? A: 350 m2/m3 * 1 m3 * 0.17 * 0.001 m * 7930 = 471.8 Kg/m3 B: 350 m2/m3 / 2 * 1 m3 * 0.17 * 0.001 m * 7930 = 235.9 Kg/m3 Why?

Since the specific surface area includes the areas of both sides of the filler sheet, it is necessary to divide by 2 to obtain the area of the filler sheet itself.
I haven’t done any proper calculations. Our designs are prepared by our designers; we just use them for production, and that’s it. Those who are familiar with this topic could please provide a detailed explanation. It will help us understand our products better. This post was last edited by Chuangxin Filler on 2009-3-20 at 18:11
Neither of these two algorithms is correct. The correct formula should be (1 - porosity) * material density.
