My preferred term is Beta-atmosphere since I find the analogy
with atmospheric pressure useful - and it arises naturally if
one starts one's analysis with sands and clays which are held
together by Alpha-atmospheric pressure in the case of coarse
sands (pF < 15 psi) and Beta-atmospheric pressure in the case
of clays, say. (pF > 15 psi).
Moin Frank,
So, you are basically changing the baseline for pressure to 15psi, but
you do still agree with the majority of the scientific community, that
all pressure is positive with relation to no pressure, and that there is
no such thing as negative pressure with relation to no pressure.
