As pump speed increases, its NPSH (Net Positive Suction Head) requirement may increase/ decrease depending on other considerations
NPSH${}_{\mathit{A}}^{}=\left(\frac{\mathit{P}\mathit{i}}{\mathit{\rho }\mathit{g}}+\frac{{\mathit{V}}_{\mathit{i}}^2}{2\mathit{g}}\right)-\frac{{\mathit{p}}_{\mathit{v}}}{\mathit{\rho }\mathit{g}}$
V${}_{\mathit{i}}$ is the average velocity at the inlet
