3.5 Consider the steady, incompressible blood flow through the vascular network as shown. Determine the magnitude and the direction of the volume flow rate through the daughter branch 2 (denoted as D3 in Figure 3.25). d1 = 100 μm v1 = 100 mm/s FIGURE 3.25 Figure for homework problem 3.5. d3 = 35 μm d2 = 75 μm v2 80 mm/s
