A wedge splits a sheet of 20°C water, as shown in Fig. P3.39. Both wedge and sheet are very long into the paper. The incoming jet is 4 cm thick at 6 m/s; exit jets are at 6 m/s. If the force required to hold the wedge stationary is F=124 N per meter of depth into the paper, what is the angle θ of the wedge?
