摘要：
In this study, the flow equations of non-Newtonian fluids through pipes and annuli have been derived using the Robertson-Stiff rheological model. From this, new and simple nomographs have been constructed to estimate the pressure-loss gradient directly for both flow-through pipes and annuli. Results from these nomographs gave excellent agreement with the results calculated from the flow equations.
