Aspects of laminar pipe flow—M. A polymer of density ρ = 0.80 g/cm3 and viscosity μ = 230 cP flows at a rate Q = 1,560 cm3/s in a horizontal pipe of diameter 10 cm. Evaluate the following, all in CGS units: (a) the mean velocity, um; (b) the Reynolds number Re, hence verifying that the flow is laminar; (c) the maximum velocity, umax; (d) the pressure drop per unit length, −dp/dz; (e) the wall shear stress, τw; (f) the Fanning friction factor, fF; and (g) the frictional dissipation F for 100 cm of pipe.
