Is there a "magic number" to calculate stacked split volume?

[scooby074]

Im wondering if there is a value you can use to calculate how much actual wood is in a average stacked, split cord?

Im trying to accurately calculate how much a stacked volume of wood will weigh for a given wood density, taking into consideration the unused space between splits. Im doing this as part of an idea I have for moving wood with my small tractor. Treating a block as a solid piece of wood as opposed wood with airspace around it changes the "do-ability" for my tractor considerably.

Would a density of 90% be a reasonable number for a typical stack? More? Less?

Most studies have come up with 80 to 85% wood with the rest being air/space.

Shortly somebody will chime in saying that is a crock but...

You can calculate the weight of the volume of wood you wish to transport with wood densities and subtracting interstitial space volumes, but I skip that step by using full cord weights available in firewood BTU charts in my calculation.

I use 4000 lbs per cord to estimate the maximum weight of a seasoned cord (128 cu.ft.) in my area, noting that green wood can be MUCH heavier.

Thanks for the info. Ill use 90% as a fill factor to allow for any "underestimations" in my cord weights .
