What is the pressure inside that tree?

  1. Apr 22, 2015 #1
    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
    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.
