We then consult another table that breaks the available static head pressure into three groups by example, the International Residential Code lists the pressures as 40-49psi, 50-60psi and 60+psi. and comparing a 3/4" pipe to a 1/2" pipe with my formula we get.. (o.75 x 0.75) / (0.5 / 0.5) = 0.5625 / 0.25 = 2.25, You challenged my results by stating we must use the formula pi x radius squaredso lets try it your way, Where:Radius = diameter/2Pi = 3.14163/4" = .75"1/2" =.5", For 3/4" radius equals .75/2= 0.375"Area = 3.1416 x (0.375 x 0.375) =A= 3,1416 x 0.140625 = 0.4417sq.in, For 1/2" radius equal .5 / 2 = 0.25A = 3.1416 x (0.25 x 0.25)A= 3.1416 x 0.06 = 0.196sq.in, Dividing the area of the 3/4" by the area of the 1/2" =0.4417 / 0.196 = 2.2535 and from my formula I got 2.25. With such a table, you can evaluate a buildings GPM as long as you know its WSFU. The larger size is necessary because soil water has solids, which could easily clog in a small size pipe.
