On the centrifugal pumps performance curves estimation using empirical equations
نویسنده
چکیده
A group of empirical equations were developed in order to estimate the performance curves (H Q, n Q, P -Q, NPSHr -Q) of a centrifugal pump, using quite small amount of pumps geometric data. The results of the present study prove that centrifugal pumps performance curves direct estimation could be accomplished without using complex mathematical models. Furthermore more, all-basic parameters affect the pump behavior are taken into account (including the installation), resulting on very good approach to basic potential performance curves, before attempting the manufacture of the prototype. These empirical equations satisfactorily provide the ability to approximate the potential performance curves of commercial centrifugal pumps.
