Thanks for sharing, very interesting.

 

Not quite sure how a tree can be 150% moisture content though?

 

Yes there were a couple of anomalies but on the whole it seemed good. Americans still don't like SI units!

 

The 150% is when the percentage is given on a dry weight basis e.g. if you have a 1m3 solid log of beech freshly felled it will weigh near as damn 1 tonne. Of this 50% will be water so on a wet weight basis the log will be 500kg of water out of the 1000kg log so mc wwb =500/1000 =0.5 or 50%. Now if you dp the same calculation on a dry weight basis you take the mass of water divided by the dry mass of wood =500/500 or 100%.

 

Do the same with a piece of pine at 60% mc wwb and you get 150% dwb. Dry weight basis is more used in the joinery trade.
