Question

Water flows around the vertical two-dimensional bend with circular streamlines as is shown in the figure below. The pressure at point (1) is measured to be pi-25 psi and the velocity across section d-a is as indicated in the table. Calculate the pressure across section o-a of the channel plz) for z = 1 ft. 2(ft) V (ft/s) 0.2 0.4 0.6 8.0 14,3 20.0 19.5 15.6 8.3 0.8 1.0 6.2 0
