The two fundamental pump designs are dynamic (centrifugal) and positive displacement. Both of these pump types are subject to cavitation which occurs if pressure inside the pump is too low, causing ...

The cavitation amplitude of 3 dB matches the prediction, where amplitude = 60 log (Xy / Xfz), Xfz = 0.81, and Xy = 0.91. The apparent discrepancy of 4 dB and 5 dB between test data and calculations ...

This subcommittee will provide a forum in which to determine and evaluate the fundamental cavitation problems in control valve applications, to establish methods for evaluating the potential for ...
