2. For an idealized slipper-pad bearing, the bottom wall moves at a constant velocity U and the upper block is fixed. Both the moving and fixed walls are non- permeable. If the velocity within the gap is, u(x, y) 1 = 2 2,4 ..? - y[y h(x)] + U[1 y h(x) where h(x) is the gap height and y is the distance from the moving wall. Please show that the pressure variation within the gap is governed by the following equation and determine A and B (20%), [A- Op. h = B
