title: Mass transfer rates in hemodialyzers--an empirical correlation.
abstract: From the experimental data on the rates of urea transfer from blood to dialysate in a test hemodialyzer, a practical equation for the effect of the hematocrit on the blood-phase urea transfer coefficient is proposed. With this equation, the overall mass transfer coefficient that takes into account the properties of the blood can be estimated for the commercially available disposable flat membrane-type and hollow fiber-type hemodialyzers from the data for a relatively simple dialysate--dialysate system.
