Pipe Friction Sizing Diameter Finder
Determine required minimum pipe inner diameter based on target GPM flow and allowable head loss constraints.
Rearranged Hazen-Williams Diameter Equation:
\( d = \left[ \frac{0.2083 \times \left(\frac{100}{C}\right)^{1.852} \times Q^{1.852} \times \left(\frac{L}{100}\right)}{h_f} \right]^{\frac{1}{4.8655}} \)
