I've yet to see a simple answer to this question :
If I'm standing in front of a growing and established eucalypt tree how many kilograms of water are in a cubic metre of the trunk ?
All i've had so far is a comparison with kiln dried wood that evades the simple question. I'm not after a 1000 word thesis on the subject.
All help will be appreciated.:?

Varies, depends on the Season and how much rain there has been recently.

Apart from "Cos'" why do you want to know?

Cheers

In the past I've been told that some fresh cut gum's are up to 4/5 water. I've no idea if this is true or not, but if you take it as an upper limit, then 80% of the m is water... which makes it up to 0.8 tonnes!

I suspect it'd be best to take that with a grain of salt. (OK, OK... several kg of salt! :wink:)

It varies widely according to the species, age, and a bit on the time of year.

According to the Forest Products Commission.

For Spotted gum Green density is about 1150 kg/m3, the air-dry density about 970 kg/m3, and basic density about 790 kg/m3


The difference between green density and basic density is the water - in the case of SG it is about 360 kg/m3.

For young Tassie blue gum its about 500 kg/m3

Sugar gum is about 350 kg/m3

Stringy is about 330 kg/m3

Jarrah is 400

Pinus radiata is 500

Marri is 550

96 words not including this sentence - is that OK?

Thanks fineboxes.
I think "cos" sums it up nicely.
