Abstract
THE viscometry of human blood has been represented by a number of empirical equations. Their usefulness has been limited to relatively narrow ranges of shear rate. Among the equations suggested, Casson's equation has been used for calculating the shear strength of blood and for describing its viscometry at shear rates below 5 sec−1 (refs. 1 and 4) (equation 1): where τ is shear stress, γ is shear rate, K is Casson viscosity, C is shear strength of suspension.
