Question
A polymer of density ρ = 0.80 g/cm 3 and viscosity μ = 230 cP flows at a rate Q =
1,560 cm 3 /s in a horizontal pipe of diameter 10 cm. Evaluate the following, all in CGS units: the answers should be the answers in the brackets.
(a) the mean velocity, um; [19.9 cm/s]
(b) the Reynolds number Re, hence verifying that the flow is laminar; [69.2]
(c) the pressure drop per unit length, -dp/dz; [14.6 dynes/cm 3]
(d) the wall shear stress, τw; [36.5 dynes/cm2 ]
(e) the Fanning friction factor, fF ; [0.23] and
(f) the frictional dissipation F for 100 cm of pipe. [1,825 cm 2/s 2 ]
