A film of paint, 3 mm thick, is applied to a flat surface that is inclined to the horizontal by an angle . If the paint is a Bingham plastic, with a yield stress of 150 dyn/cm2 , a limiting viscosity of 65 cP, and an SG of 1.3, how large would the angle have to be before the paint would start to run? At this angle, what would the shear rate be if the paint follows the power law model instead, with a flow index of 0.6 and a consistency coefficient of 215 (in cgs units)?
