7.24. If a zone of unestablished flow may be idealized to the extent shown and the centerline may be treated as a streamline in an ideal fluid, calculate the drag force exerted by the sidewalls (between sections 1 and 2) on the fluid if the flow is: (a) two-dimensional and 0.3 m wide normal to the paper and (b) axisymmetric. The fluid flowing has specific gravity 0.90. 21 Parabola

Question 2. A fluid of density p is contained in a cylinder of radius R as shown in the Figure below. The cylinder and the fluid are both spinning at an angular velocity w. Due to the spin, the difference in elevation of the fluid's free surface between the rim of the cylinder and its centre is h. Taking the acceleration due to gravity as g, answer the following, while showing all your work: (a) If h is thought to be a function of the other parameters in the problem (R, p, g, and w), generate all the non-dimensional parameters in the problem without choosing the acceleration due to gravity as a repeating variable. (b) Show that at least one of the non-dimensional parameters can be recast as the Froude number for the problem. Additionally, show the functional relationship between the independent and dependent non-dimensional parameters. (c) Through an experimental design of your choice, explain how and with how many experiments, you would determine the functional form of the…
