Hi all,
we have a vessel (Diesel salt drier) here which is rated for an internal pressure of 110 psig and an external pressure of 2.5 psia. I am sizing a relief valve for this vessel and there are concerns about the vacuum generation on the vessel by a centrifugal pump which takes suction from the top of the vessel. The logic says that the pump will cavitate and stop, but
The quesiton is -
Is there a way to calculate the max vacuum a centrifugal pump can pull before it cavitates and stops? The fluid is diesel with a vapor pressure of 0.001 psia @ 110 °F.
Please let me know if any references are available.
Thanks,
SM
