HI 9.6.6 - Physical Model Study for Pump Inlet Piping

HI 9.6.6 - Physical Model Study for Pump Inlet Piping

HI 9.6.6 - Physical Model Study for Pump Inlet Piping

(OP)
I am looking for information on what instrumentation and testing criteria would apply to physical model studies for centrifugal pump inlet piping.

For pump inlet piping conditions that do not comply with the requirements of HI 9.6.6 the standard appears to allow for a physical model study to be performed. I am interested in learning what criteria need to be measured and what the passing test criteria would be for this. I am wondering if these criteria could be field applied to an existing installation.

I am grateful for any input/feedback that you may be able to offer! Thank you!

(Note: I originally posted this under the Pipelines, Piping and Fluid Mechanics engineering Forum however I now see that the pump forum seems more appropriate for this subject matter)

RE: HI 9.6.6 - Physical Model Study for Pump Inlet Piping

All the measurements, swirl angle, rotations, time averaged rotations, etc are all laid out clearly in HI 9.8.

This can be scaled to the existing model as long as the model has a minimum Weber and Reynolds. Then Froude number should be matched.

Thanks nondimensional. I'll take a read through 9.8.
