This is our average, it is figured out of an average of our daily analysis...Lightning wrote:Oh thank you sir, just curious more than anything else. Also, maybe you could shed some light on how they come up with the figures. Do they measure a single square foot? Or do they measure the volume of a large quantity and divide?

Cool. I had previously done measurements on a load of nut size coal a few years ago and came up with 59-60 pounds per cubic foot. Even though it wasn't Lehigh, maybe I was pretty closeLehighanthraciteMatt wrote: Our averages are as follows for Pea, Nut, and Stove.

Your figures show nut size to take up a hair over 34 cubic feet per ton..

Yes, see for example Coal Bin Lumber, Mon Jun 10, 2013 6:43 am. Elsewhere I believe he said this could be affected by vibration, so if the Lehigh testing includes steps to "settle" the sampled coal, that might cause a different result from Richard's observations from the loadout. For sizing a bin, I think the relevant density is Richard's, since most bins don't allow you to settle the coal through shaking/vibration.Lightning wrote:Actually, I thought Richard said that the stove size was most dense and the rice was the least.

i'll testify for the nut figure. the 23.1 ton load i received last Nov. fit very nicely in 800 cu ft of space. which means it was much closer to the 58.4 #'s per c.f. than the 50 #'s per c.f. i had allowed for.
in the begining i thought i had been seriously shorted till i started digging and found that "50" is just a good round number commonly quoted as a precaution to assure room for a given purchase order regardless of size rather than a "ruler" to gauge quantity accurately.
i also had the certified scale slip stating 23.1 tons were loaded on that truck so i had to very closely measure my filled area and found that this coal must indeed weigh more per c. f. than i thought.
