Waste activated sludge can be described as a Newtonian fluid with a kinematic viscosity of 20 x 10 ft/sec. At the same temperature, the kinematic viscosity v of water is 10 ft/sec. The relative roughness of the piping system is 0.001. The pressure drop for flow of water at a Reynolds number of 10' in this piping system was determined to be 1.0 psi. If waste activated sludge flows at the same velocity through the piping" system, the pressure drop (psi) is most nearly:
