Cord wood stack calculation help

[Bob_z_l]

I have searched and can't find a good answer.

 

If I had a stack of cord wood lengths approx 10m cube --- 2 x 5 x 1

How much do I allow as airspace when I calulate the volume of wood?

 

I have the remaining data to work out the weight of the wood wet/dry...etc.

 

Anyone?

 

 

Thanks

Is it softwood bars or hardwood cabbage wiggles?

Hardwood....moderately straight sticks

[bilke_user]

With softwood stacks half and half

 

Hardwood wiggles will be a good bit less

I had calculated 60% wood 40% air so I'll reverse it and try again.

 

Cheers

I've used 30% for air gaps assuming logs are straight and even. I got this figure from some EU manual on timber but can't recall exactly at the moment.

Nonsense and also officially wrong.

 

Good straight softwood generally is 0.7 - 0.75.

Hardwood typically 0.55 or 0.6 for straighter stuff.

 

See FC Blue Book if you don't believe me.

We base almost all decent hardwood stacks at 55% timber 45% air and as a general rule of thumb its not too far out.
