Abstract: Viscosity measurements were made using a coaxial rotating cylinder viscometer for blood having various volume fractions of red cells. A method is described for analyzing non Newtonian blood viscosity in low shear rates by taking account of an increase or a decrease in size of red cell aggregates induced by shear. Our results are compared with empirical formulae presented by Scott Blair. Weaver Evans Walder and Thurston.
