Transcribed Image Text:Q/ Consider the film flow of a power-law fluid with parameters к and n and density p down a plate inclined at angle with respect to the horizontal. If the film thickness is H: a. Derive an expression for the resulting velocity profile x as a function of y (distance from the plate), H, к, n, g, p, and 0 b. Sketch three representative velocity profiles (each having, for simplicity, the same maximum velocity, which in practice would mean different values of x), for n < 1, n = 1, and n > 1, and comment briefly on the important features. Power law fluid model is given as: T, = m(-dvx)" where m=k Continuity Equation, Cartesian coordinates dr др at Uz др ǝx др +P + บบ บ ax J+ ลง← + อ! მაქ = Iz Continuity Equation, cylindrical coordinates др 1 (prvr) 1 + at (pv) + + ǝr T a0 ǝ(pv) Dz = 0 Continuity Equation, spherical coordinates др at 1 (pr²vr) 1 + + -2 Ər r sin 0 (pvo sin 0) a0 1 2 (ρυς) + = 0 r sin 0 მი ☐
