Figure 12. Distribution of the hydrodynamic friction coefficient X in the Newtonian model (a) and non-Newtonian model in the case when TPMA=1.0 (b), 2.5 (c ) and 4.0 (d) g/ 100ml.

The influence of the protein level, measured by TPMA, is evidently weaker. Assuming a variation of TPMA in the range 1.0 ... 4.0 g/100 ml, in the case of the average velocity 0.1 m/s, it varies from 0.316 ... 0.393, but for the average velocity 0.5 m/s (the interval is as follows: 0.044 ... 0.054). It means that deviations less than 20% occur when for the case of hematocryte these deviations is up to 50%.

Finally, at the end of the influence analysis of flow parameters, it should be added that a particular important and general statement can be established. For example, let's consider the equation (31) describing the velocity profile in the cross-section of a vessel in relation to the average velocity and let us investigate these ratio as the hematocritic numbers decreases:
