$3\mathrm{.}6\mathrm{.}20$ WP The pressure and average velocity at point $\backslash ($ A $\backslash )$ in the pipe shown in Fig. P$3\mathrm{.}6\mathrm{.}20$ are $16\mathrm{.}0$ psia and $\backslash (4\mathrm{.}0\backslash$mathrm$\{$ft$\}/\backslash$mathrm$\{$s$\}\backslash ),$ respectively. Find the height $\backslash ($ h $\backslash )$ and the pressure and average velocity at point $\backslash ($ B $\backslash ).$ Fluid fills the $1-$in$.-$diameter discharge pipe.
