Water flows through a horizontal pipe bend and exits to the atmosphere, as shown. Find $($a$)$ the velocity at the exit, $\backslash ($ V$\_\{2\}\backslash ),($b$)$ the gage pressure at the pipe inlet, $\backslash ($ P$\_\{1\}\backslash ),$ and $($c$)$ the force in the x$-$direction on the water as it flows through the bend.

Given:
