Document Summary

Cbe 2221: for fluid 1: 1 : 1 = (d /dy)top surface = (0. 4)(3-2/0. 02) = 20 n/m2. Similary for fluid 2 : 2 : 2 = (d /dy)bottom surface = 20 n/m2. Thus, 1/ 2 = 1: = (d /dy) (d /dy) = d/dy{ (2y/h y2/h2)} = (2/h-2y/h2) At the fixed surface, y = 0 ; d /dy = 2u/h. = (2u/h) =4. 48 x10-2 n/m2 acting in the direction of the flow: = (d /dy) d /dy = c1 +3c2y2 = 153 + (3) (4350) y2. Air at 70 f = 3. 82 x 10-7 lb. s/ft2 this at wall, y =0. For 70 mm hg, p = 9. 31 kpa: for 120 mm hg , p = (15. 96 x 103) (1. 45 x 10-4) = 2. 32 psi.
