WebThe sandpaper decreases in surface roughness (Sa) and particle size as the grit increases, as expected. The Sa ranged from 42.37 μm to 3.639 μm. The particle size ranges from 127 ± 48.7 to 21.27 ± 8.35. Larger particles and high height variations create stronger abrasive action on surfaces as opposed to smaller particles with low height ... WebAnswer (1 of 3): I take it that you have a certain grain of sand in mind. Finding the mass is very easy. Use a calibrated microbalance. The grain might have a mass of a milligram or so, depending on size. (Typical sand grains have a particle density of 2 to 3 T/m3.) To determine the volume, you...
