Question

34. A coal slurry is found to behave as a power law fluid, with a flow index of 0.3, a specific gravity of 1.5, and an apparent viscosity of 70 cP at a shear rate of 100/s. What volumetric flowrate of this fluid would be required to reach turbulent flow in a 1/2 in. ID smooth pipe, which is 15 ft long? What is the pressure drop in the pipe (in psi) under these conditions? Please show all work, thank you!
