This is a continuation of the earlier work on the I-42B pump presented by Sachdeva1 . The dynamic model developed earlier is extended to include axial geometries. Correlations are developed for CD/rb -- the only correlating factor required to complete the model. The performance of radial C-72 and axial K-70 pumps under gassy conditions is studied. Besides the dynamic model, a simple correlation (Model 2) for predicting the pressure rise per stage is also developed for the C-72, K-70 and I-42 pumps.
