12.4 The Reynolds equation for squeeze film action in an incompressible lubri- cant contained between two nonparallel bearing surfaces of infinite width approaching each other with a velocity wo is d dp (d) = -12nowo dx Side leakage is neglected. Determine the expression for the time it takes for the minimum film thickness in an inclined-pad bearing to fall from an initial value ho, to a final value ho,2 under the action of a constant load per unit width w₂. The assumptions in the analysis should be clearly stated. If the shoulder height is initially equal to the outlet film thickness on a 1.5-in-square pad, calculate the time taken for a load of 500 lbf on the pad to reduce the minimum film thickness from 0.001 in. to 0.0001 in. if the lubricant viscosity is 0.5 P.
