Unformatted text preview: plate held parallel to a moving surface as shown. The plate has a step that prevents Fow through the gap. The height of the gap is h , and the width of the bearing is w . The Fuid is of density and viscosity and the Fow is fully laminar. The velocity of the moving surface is V o . (a) Calculate the load F supported by the bearing in terms of , V o , l , h . (b) Calculate the ratio of the drag force D on the moving surface to the load F . (c) If V o = 20 ft/sec., h = 103 ft., l = 0 . 5 ft and we use SAE 30 oil at a temperature of 150 o (specic gravity =0 . 85), calculate F and D/F ....
