Pump head rating

Input(s)

$\mathrm{n}_{\mathrm{p}}$: Number of Pitches of Stator (unitless)

$\Delta \mathrm{p}$: Head Rating Developed into an Elementary Cavity (psi)

Output(s)

4P: Pump Head Rating (psi)

Formula(s)

$$ \Delta \mathrm{P}=\left(2 * \mathrm{n}_{\mathrm{p}}-1\right) * \Delta \mathrm{p} $$
