The fluid flow through the pump is characterized by the following properties:

LaTeX Math Inline
body--uriencoded--p_%7Bin%7D

intake flow pressure

LaTeX Math Inline
body--uriencoded--p_%7Bout%7D

discharge flow pressure

LaTeX Math Inline
body--uriencoded--\Delta p = p_%7Bout%7D - p_%7Bin%7D

pump pressure gain 

LaTeX Math Inline
body--uriencoded--q = q_%7Bin%7D

volumetric flowrate at intake

LaTeX Math Inline
body--uriencoded--\dot m = q \cdot \rho (p_%7Bin%7D)

mass flowrate through the pump

LaTeX Math Inline
body\rho (p)

fluid density at a given pressure 

LaTeX Math Inline
bodyp


The two major properties of the pump are:

LaTeX Math Inline
body--uriencoded--\Delta p_%7Bmax%7D

maximum pump pressure gain

LaTeX Math Inline
body--uriencoded--q_%7Bmax%7D

maximum flowrate


In most practical cases the pump pressure gain is the function of the pump volumetric flowrate and only depends on the pump specifications.

This function is usually pictured graphically as Pump Characteristic Curve (see Fig. 1).
