Abstract
Operational problems can often be traced back to a non-optimum - or even downright wrong - pump selection. An unsuitable selection may result from insufficient knowledge of pump operation and installation conditions or from not giving them careful consideration and analysis.

Notes
- 1.
Equation (T15.1.3) was derived from a graph in [B.17], Eqs. (T15.1.4 to T15.1.6) follow from Eq. (T15.1.3).
- 2.
Maximum values of w1q/w1 are close below 1.0. In a correctly designed hydraulic the ratio c3q/c2 follows from the collector calculation according to Chap. 7. Low values of c3q/c2 point to a non-optimum design and a design check would be indicated.
