Abstract: An approximate Casson model for tube flow is derived based on order of magnitude considerations. The approximation is principally of value for tube flow measurements in which the pressure drop and volumetric flow rate are experimentally measured. Data for heparinized bovine blood and silica suspensions are in good agreement with the approximate expression. The model is compared with an approximation proposed earlier by Merrill et al.
