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)

$$ \mathrm{P}_{\mathrm{c}}=\mathrm{P}_{\mathrm{p}} *\left(\frac{\mathrm{q}_{\mathrm{n}}}{\mathrm{q}_{\mathrm{o}}}\right)^{2} $$
