WebIt is known that the resistance to flow through a cylindrical tube or vessel depends on several factors (described by Poiseuille) including: 1) radius, 2) length, 3) viscosity of the fluid (blood), and 4) inherent resistance to flow, as follows: where r = inside radius of the vessel, L = vessel length, and η = blood viscosity. WebComparing the Bulk Flow Law to Ohm’s Law of electricity (ﬂow vs. current, pressure gradient vs. voltage gradient, hemodynamic resistance vs. electri-cal resistance) helps to orient students to something they already know. We can immediately demonstrate the utility of the Bulk Flow Law by giving an example CO 5 MAP 2 RAP TPR < MAP TPR (2) how are all unit fractions different
