https://doi.org/10.1007/978-3-642-96657-6When a centrifugal pump is used for transporting a fluid with a viscosity much higher than cold water, additional losses impair the performance. Therefore, the pump characteristics determined for water must not be applied without correction to pumping highly viscous fluids as encountered for example in the oil and process industry.

Biomechanics of the Osteoarthritic Hip,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.

While the radial force is determined by the pressure distribution . the axial force is governed by the flow through the impeller sidewall gaps and the resulting pressure distributions on the shrouds.

How the Resultant Force R May be Reduced,tions are processes where a large amount of fluid energy is dissipated in valves or other throttling devices. In some processes dissolved gases separate from the fluid or liquid is flashed into steam during the expansion. Higher energy differences are then available for power recovery than in pure liquid flow, Chap. 13.3.
