Chapter 9, Problem 9.58(choose chapter or problem)
The plate shown in the figure is weighted at the bottom so it will fall stably and steadily in a liquid. The weight of the plate in air is 23.5 N, and the plate has a volun1e of 0.002 m3 Estimate its falling speed in freshwater at 20C. The boundary layer is normal; that is, it is not tripped at the leading edge. In this problem, the final falling speed (terminal velocity) occurs when the weight is equal to the sum of the skin friction and buoyancy. I , w = B + F, = ..., + 2 pu s Hints: Find the final falling speed. This problem requires an iterative solution.
