Measuring stacked timber !

[garyf]

I recall an old Forester telling me it was possible to estimate the tonnage of stacked timber.I can't remember the length of the stack, but it was 2 metre lengths by 2 metres in height.I think it was 10 metres long by 2 metres high by 2 metres in length was about 20 tonnes.Does this sound right ? It was stacked softwood pulp.

I am no expert but if its beech a solid cubic metre weighs a tonne when green. To get a solid tonne you allow something like 45% air space. So you are about right.

Hi, in the Foresters Companion theres a table which reads something like this:

 

 

8ft (length) x 4ft (Height)x 4ft (width) = 3.62 m cubed

12 x 3 x 4 = 4.08

14 x 3 x 3 = 3.56

 

With the volume known you can find out the density per m squared from a ref book for instance at 15% moisture:

Ash is 660 kg/m cubed

Beech 740

Birch 720

Elm (English) 560

Douglas Fir 480-550

Mahogany 545

Pine (Pitch) 640

Pine (scots) 530

Norway Spruce 430

 

Of course air space and the moisture contents will differ.

Hope this helps and makes a bit of sense haha
