A coal suspension is found to behave as a power law fluid, with a flow index of 0.4 , a specific gravity of 1.5 , and an apparent viscosity of $90 \mathrm{cP}$ at a shear rate of $100 \mathrm{~s}^{-1}$. What would the volumetric flow rate of this suspension be in a $15 \mathrm{ft}$ long, 5/8 in. ID smooth tube, with a driving force of 60 psi across the tube? What is the Reynolds number for the flow under these conditions?
