Unformatted text preview: the fluid weight. Use the NavierStokes equations to derive an expression for the velocity distribution between the plates. Assume laminar. 11/11/2009 Midterm 2 Review problems 057:020 Fall 2009 4. Dimensional analysis Molasses is stored in a tank 15 m in diameter. It leaves the tank under the action of gravity through a pipe at the tank bottom and flows to a bottling machine. It is imperative that no air be allowed in the system, which is a possibility when the level of molasses in the tank is so low that a vortex forms over the discharge pipe (Fig. 4.5). A study is made of the system with a onefifth scale model using water as the fluid medium. Measurements made on the model indicate that when h = 8 cm a vortex forms. What is the corresponding depth on the prototype? Take the density of molasses to be 1300 kg/m 3 . 11/11/2009 Midterm 2 Review problems 057:020 Fall 2009 Solutions 1. 2. 3. 11/11/2009 Midterm 2 Review problems 057:020 Fall 2009 4. gl V gl V M M =...
