New pump circulating pressure
Input(s)
\(\mathrm{P}_{\mathrm{p}}\): Present Circulating Pressure (psi)
\(\mathrm{q}_{\mathrm{n}}\): New Pump Rate (spm)
\(\mathrm{q}_{\mathrm{o}}\): Old Pump Rate \((\mathrm{spm})\)
Output(s)
\(P_{\mathrm{c}}\): New Circulating Pressure (psi)
Formula(s)
\[
\mathrm{P}_{\mathrm{c}}=\mathrm{P}_{\mathrm{p}} *\left(\frac{\mathrm{q}_{\mathrm{n}}}{\mathrm{q}_{\mathrm{o}}}\right)^{2}
\]
