book: transport phenomena 2nd edition author:byron bird page111 ex: 3c.3 deformation of a fluid line in couette flow Prolem Detail: A fluid is contained in the annular space between two cylinders of radial Kr and r. The inner cylinder is made to rotate angular velocity of Wi. Consider a line of fluid paricles in the plane z=0 extending from the inner cylinder to the outer cylinder and initially located at O(sita) = 0, normal to the two surface. How does this fluid deform into a curve O(sita) (r,t), what is the length l of the curve after N revolutions of the inner cylinder? 請各位高手們再次幫忙囉!! 有解的話可以麻煩回到我的信箱或是[email protected] 感謝!!~~ 真的有收到您的解的話,一定會好好感謝您的!! -- ☆ [Origin:椰林風情] [From: chap254-198.resnet.stonybro] [Login: **] [Post: 22]
