Gerard –
That’s funny.
Are you referring to my Q=P(1+6e/L)/(W*L) model?
Soil supports? I don’t need no stinking soil supports!
:o) :o)
If so, I guess I could change it to:
Q= P(1+6e/L)/(W*L’)
Where L’ is less than L by the ineffective with of mat in contact with the soil due to the pipe (say 12”-15” or so).

In your mat foundation model, you may want to remove the soil supports…
