What is the pressure inside that tree?

SUMMARY

The discussion centers on predicting internal pressure in large trees based on height and circumference measurements. The participant, with a background in horticulture and tree specialization, references the work of Prof. Dr. Claus Mattheck and highlights the importance of osmotic pressure, capillary action, and transpiration suction in this context. The inquiry seeks scientific studies related to internal tree pressures and suggests that hydrostatic measurements in plant physiology could provide insights. The use of trigonometry for height assessment is also mentioned as a practical approach.

PREREQUISITES
  • Understanding of plant physiology, specifically osmotic pressure and transpiration.
  • Familiarity with hydrostatic measurements in botanical contexts.
  • Basic knowledge of trigonometry for height assessment.
  • Awareness of biomechanics principles related to trees.
NEXT STEPS
  • Research scientific studies on internal tree pressures and their measurement techniques.
  • Explore hydrostatic measurement methods in plant physiology.
  • Investigate the biomechanics of trees as outlined by Prof. Dr. Claus Mattheck.
  • Learn about the effects of capillary action on tree health and structure.
USEFUL FOR

Horticulturists, arborists, plant physiologists, and anyone interested in the biomechanics and internal dynamics of trees.

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

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.
