$3\mathrm{.}3\mathrm{.}4$ Water flows around the vertical two$-$dimensional bend with circular streamlines, as is shown in Fig. P$3\mathrm{.}3\mathrm{.}4.$ The pressure at point $(1)$ is measured to be p$1=25$ psi, and the velocity across section a$$a is as indicated in the table. Calculate and plot the pressure across section a$$a of the channel $[$p$=$p$($z$)$for$0$z$2$ft$].$
