Consider a series of turning vanes struck by a continuous jet of water that leaves a 50-mm-diameter nozzle at constant speed, V= 86.6 m/s. The vanes move with constant speed, U = 50 m/s. Note that all the mass flow leaving the jet crosses the vanes. The curvature of the vanes is described by angles a = 30' and 02 = 45'. Evaluate the nozzle angle, a, required to ensure that the jet enters tangent to the leading edge of each vane. Calculate the force that must be applied to maintain the vane speed constant.
