摘要：
This work proposes a method for evaluating the Darcy friction factor and the Nusselt number for fully developed laminar convective flow of Carreau fluids through straight circular tube under a constant heat flux. General mathematical formula for the Darcy fiction factor and the Nusselt number has been derived. This work has found that both the Darcy friction factor and the Nusselt number vary along with the flow rate from their Newtonian to Power law values in a similar way. Then, they have been evaluated for the Carreau fluids with various constants.
