Calculation of a Centrifugal Pump
The calculation is based on fluid hydraulics and today's knowledge of Centrifugal Pumps. This implies that the results are independent of Pump manufacturers and are very useful during conceptual studies, basic engineering and as a starting point for requisitions. During the evaluation of quotations the results provide an independent benchmark.
