Problem

At the toe of a spillway the flow is h1=0.15 mh_1 = 0.15\,\mathrm{m} deep with speed u1=6.0 m s−1u_1 = 6.0\,\mathrm{m\,s^{-1}}, and a hydraulic jump forms. Find ((a)) the upstream Froude number Fr1\mathrm{Fr}_1 and the downstream depth h2h_2; ((b)) the downstream velocity u2u_2; ((c)) the head lost across the jump.
