Experimental investigations have been carried out to evaluate the two‐phase pressure drop data across different types of horizontal bends for gas‐non‐Newtonian liquid flow. The non‐Newtonian liquids used were different concentrations of the sodium salt of carboxymethyl cellulose (SCMC) which behaved like pseudoplastic fluids. Correlations have been developed to predict the gas‐non‐Newtonian liquid two‐phase friction factor as a function of various physical and dynamic parameters of the system. Statistical analysis of the correlations suggests that the correlations are of acceptable accuracy.
