A model is proposed for the transfer of heat to non-Newtonian power-law fluids flowing in heated horizontal pipes. Comparisons with the existing models, based on the absolute-percent-arithmetic-average-deviation and the percent-standard-deviation, show that under the transitional and turbulent flow regimes the proposed correlation fits the experimental data more accurately over a wide range of flow behavior index and there are no restrictions for its use when applied to pseudoplastic fluids.
