Would you be good enough to add a few more tests:</div><div><br></div><div><span class="Apple-tab-span" style="white-space:pre"> </span>a. Measure (ml or gm) the amount of water (and/or acetone) you can add to the container full of sand. (I see relative density of .785 for acetone)</div><div><br></div><div> b. Same for sand replaced by pellets, even if the pellets are ruined (but try to make the weight gain measurement as fast as possible (see how much you can both add and drain). But perhaps they can be waterproofed with only a gram or two of waxy material.</div><div><span class="Apple-tab-span" style="white-space:pre"> </span></div><div><span class="Apple-tab-span" style="white-space:pre"> </span>c. Same when you mix sand and pellets (my preference is to start with a liter of only pellets, then first see how much sand you can get in [by shaking], weigh and then see how much water (and or acetone) can be added).</div><div><br></div><div> 2. I agree with Andrew Heggie that a void space of 52% sounds high. Can you specify the diameter of the pellets and an average pellet length. Manufacturer? Any spec on source material?</div><div><br></div><div> 3. If you have to start over, let’s use a volume of “exactly” 1 liter (water weight = 1 kg), for all cases (to simplify the computations).</div><div><br></div><div> 4. We should be able to get the same answer for pellet density regardless of how hard we try to increase the bulk densities (Alex’ point). </div><div><br></div><div>Thanks in advance.</div><div><br></div><div><br></div><div>Ron</div><div><br><div><div>On Mar 8, 2014, at 3:53 PM, Frank Shields <<a href="mailto:frank@compostlab.com">frank@compostlab.com</a>> wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite"><div lang="EN-US" link="blue" vlink="purple" style="font-family: Helvetica;
