Measuring void fraction
Measuring void fraction
(OP)
Hello -
I want to measure of void fraction of mulch. I know if I can get the bulk density and the displacement of a known mass of mulch then I can figure the void fraction.
Mulch floats. I want to submerge a 1 lb sample of mulch, but need to keep it submerged to measure the water displaced. If I use a weight to keep the mulch submerged, then I can figure the displace.
I'm wondering what methods are typical for measuring void fraction.
Thanks -
Rob

RE: Measuring void fraction
I'm figuring take 1 lb exact of same material and place in filled widemouth 2 L beaker. Insert material and measure volume required to top back off.
How you reckon we get the mulch under water?
Thanks for the help.
