Chapter 9, Problem 9.48(choose chapter or problem)
Determine the drag on a small circular disk of 0.01-ft diametermoving 0.01 ft/s through oil with a specific gravity of 0.87 anda viscosity 10,000 times that of water. The disk is oriented normalto the upstream velocity. By what percent is the drag reduced if thedisk is oriented parallel to the flow?
