Question

Working at DuPont, you need to transfer a power-law fluid through a horizontal pipeline (ID = 10 cm) from tank A to tank B with a specified volumetric flow rate of 2 liter/s. Your team decided to use a cone–plate viscometer (cone angle = 0.45°) to measure the viscosity of the sample fluid being transferred, and the results suggested viscosities of 0.250 Pa·s at 10 rpm and 0.050 Pa·s at 100 rpm. Assuming that the pipeline is approximately 100 m, determine the pressure required send the fluid through.
