We assumed frictionless fl ow in solving the bump case, Prob. P10.65, for which V2 5 1.21 m/s and y2 5 0.826 m over the crest when hmax 5 15 cm, V1 5 1 m/s, and y1 5 1 m. However, if the bump is long and rough, friction may be important. Repeat Prob. P10.65 for the same bump shape, h 5 0.5hmax[1 2 cos (2x/L)], to compute conditions (a) at the crest and (b) at the end of the bump, x 5 L. Let hmax 5 15 cm and L 5 100 m, and assume a clean-earth surface
