Dear All,,
I was going through the below TOTM by Jon Campell discussing the impact of viscosity increase on pump performance curves. Figure 2 in below post is discussing that for flow of 0.6& Q BEP, there will be a comparative increase in the delivered head compared to the base case curve. Do you agree that in this case, the delivered pump's discharge pressure could be higher for the same suction pressure.
can we rely on suction correction figures and factors for estimating the viscosity effect while having a base case pump curve represented based on water test.
I understand we have to go back to vendor to check, however, there are situations where overcooling may cause wax formation in crude and exponential increase in viscosity that needs to be checked with respect to the impact on system's hydraulics.
regards,
