Thought it might be a good idea to start collecting some of the specific formulas and best "Rules of thumb" in one location. I know there are tons of things that could be stuck here, so maybe we put the resulting list into a PDF later? Here are a few I think I've seen on the boards already:
1 Foot Height = 0.434 PSI (Gravity feed pressure)
Ideal Sewage pipe decline 1ft:4 inches of rise.
(to little and backed up sewer, to much and solids get stuck)
Basic Electricity Chart
E=IxR
E=P/I
E=Squareroot of (PxR)
I=E/R
I=P/E
I=Squareroot of (P/R)
R=E/I
R=P/I-squared
R=E-Squared/P
P=IxE
P=I-squared x R
P=E-Squared/R
