Note that a milliliter is the same volume as a cubic centimeter, so 1 g/ml is the same as 1 g/cm 3. Below you will find important tips for the success of your density determination. What is Bulk Density? Bulk density is also used to convert between weight and volume of soil. Bulk density is defined as the mass of a bulk material divided by the volume occupied by that material. Mass is a measure of how much matter there is within an object or liquid while density expresses how much mass there is per a certain amount of volume. The bulk density measurement should be performed at the soil surface and/or in a compacted zone (plow pan, etc.) Because the interparticulate interactions influencing the bulking properties of a powder are also the interactions that interfere with powder flow, a comparison of the bulk and tapped densities can give a measure of the relative importance of these interactions in a given powder. Both methods use different apparatus but use the formula . These powders can range from sugars, spices and flours to end products like instant coffee and protein powder.1. The higher shear force which occurs between the fluid and the tube wall results in slowing down the oscillation frequency, thus showing a higher density value.
