4.) You are working on a bioreactor for culturing a network of cylindrical blood vessels and need to perfuse this network with growth media using pressure driven flow. a.) Calculate the resistance for flow of a fluid with dynamic viscosity of 4 * 10-3 Pa * s at 37°C for the combination of tubes organized as shown to the right, what is the total resistance for the system? You can use units of $\frac{Pa*s}{cm^3}$ and ignore junctional effects. All vessels in a section are the same dimensions. b.) If the pressure drop across the network is 100Pa, what is the flow rate in mL/min? (2x) Radius = 0.5cm Length = 30cm (3x) Radius = 0.2cm Length = 60cm (2x) Radius = 0.5cm Length = 30cm P1 P2
