Non-newtonian liquid flow through globe and gate valves

Experimental data on the pressure drop across 1/2-in. globe and gate valves in the horizontal plane for non-Newtonian pseudoplastic fluids in laminar flow are presented. Generalized correlations in terms of the various physical and dynamic variables of the system have been developed for prediction of the frictional pressure drop for each valve. Statistical analysis of the correlations suggest that they are of acceptable accuracy.
