What is the pressure inside that tree?

[Nat Collett]

Hi,
Having a background of horticulture training (NZTCH) and tree specialisation (NSW Arbor Techniques & Tree Surgery), I'm very interested in biomechanics so enjoy books written by authors like Prof. Dr. Claus Mattheck
http://www.mattheck.de/english/english2.htm
My question is:
Given a height in metres, and a circumference in metres, is the internal pressure predictable in a big tree?
Well aware of the combination of osmotic pressure, capillary action and transpiration suction that provide this pressure; but how to guesstimate? We can assess the height of a tree without climbing it (roughly accurate).
Has anyone ever come across any scientific study on internal tree pressures?

I don't know anything about the pressure, but assuming there is line of sight to the top of the tree from some distance away, getting the height is simple trig.

This is Plant Physiology - hydrostatic measurements are possible. See: http://5e.plantphys.net/article.php?ch=&id=100
