P3.114 Water flows through a circular nozzle, exits into the air as a jet,and strikes a plate, as shown in Fig. P3.114. The force required to hold the plate steady is 70 N. Assuming steady, frictionless,one-dimensional flow, estimate (a) the velocities at sections(1) and (2) and (b) the mercury manometer reading h.
