a. Blood flows through an experimental setup tube at 14.5 m/s with a diameter equal to 500m. What is the friction factor associated with this flow? b. In another part of the setup with the same diameter, the Reynolds number is 20,000 and the roughness is 15 m. Find the new friction factor associated with the later part of the setup. c. The volumetric flow rate of a different fluid (density=1000kg/m3, viscosity=6 cP) in the setup with a circular cross-section (D=60 cm) of is 5m3/s. The surface roughness of the pipe is 0.6 mm. Determine the friction factor associated with this flow
