See� table above. <br /> TOTAL Total length (PIPE + FT'NG'S) <br /> Pt Total pressure (psi) at fitting <br /> pe Pressure due to change in elevation <br /> where Pe = 0. 433 x change in elevation <br /> Pf Friction loss (psi) to fitting <br /> where Pf = 1 x 4 . 52 x (Q/C) ^1 . 85 / ID^4 . 87 <br /> Pv Velocity pressure (psi) <br /> where Pv = O . Oq1123 x Q^2/ID^4 <br /> Pn Normal pressure (psi) , where Pn = Pt - Pv <br /> NOTES: <br /> - Pressures are balanced t�o 0.01 psi . Pressures are listed to <br /> 0. 1 psi. Addition may vary by 0. 1 psi due to accumulation of <br /> round off. <br /> - Calculations conform to 'NFPA 13. <br /> - Velocity Pressures are not considered in these Calculations <br />
