WebApr 13, 2024 · Red blood cells (RBCs) are magnetically repelled due to their inherent paramagnetic composition. From Fig. 4, we can inferred that the velocity profile decreases as the hematocrit parameter \(h_m\) enhances. The reduction in velocity profile is due to the increase in the blood viscosity. WebSimilarly, if the viscosity of the blood increases 2-fold, the resistance to flow will increase 2 fold. In contrast, an increase in diameter (or radius) reduces resistance. The change in diameter alters resistance to the fourth power of the change in diameter. For example, a 2-fold increase in diameter decreases resistance by 16-fold! chino brown high waisted pants women
