You want to use a viscous Newtonian fluid to transport small granite particles through a horizontal $1 \mathrm{in}$. ID $100 \mathrm{ft}$ long pipeline. The granite particles have a diameter of $1.5 \mathrm{~mm}$ and $S G=4.0$. The $\mathrm{SG}$ of the fluid can be assumed to be 0.95 . The fluid should be pumped as fast as possible, to minimize settling of the particles in the pipe, but must be kept in laminar flow, so you design the system to operate at a pipe Reynolds number of 1000. The flow rate must be fast enough that the particles will not settle at a distance greater than 1/2 the ID of the pipe, from the entrance to the exit. What should the viscosity of the fluid be, and what should the flow rate be (in gpm) at which it is pumped through the pipe?
