A biofluid with a density of 1080 kg/m³ flows through the converging network as shown with circular inlets or outlets. Use RTT and conservation of mass. (A) Given diameters D₁ = 15 μm, D₂ = 9 μm and D3 = 24 μm, with velocity V₁ = 5 mm/si and V₂ = 8 mm/s j, determine the magnitude of V3 right at the exit point in branch 3. Assuming steady and incompressible flow. (B) Using the same geometry as above, if V3 must be maintained at 10 mm/s, what is the rate of change in volume in the box above? D1 V₁ D₂ V₂ D3 V3
