Critical flow rate for flow regime change
Input(s)
\(\mathrm{V}_{\mathrm{c}}\): Critical Velocity \((\mathrm{ft} / \mathrm{s})\)
\(\mathrm{D}_{\mathrm{i}}\): Integral Diameter of Pipe (in.)
Output(s)
Qc: Critical Flow Rate \((\mathrm{gpm})\)
Formula(s)
\[
\mathrm{Q}_{\mathrm{c}}=2.448 * \mathrm{~V}_{\mathrm{c}} *\left(\mathrm{D}_{\mathrm{i}}^{2}\right)
\]
