When water is flowing in a steady state through a $45$ curve. At the entrance of the curve

$($section $1),$ the gauge pressure is $120$KPa. The water discharges at atmospheric pressure. Note:

The velocity V$1=3\mathrm{.}05\frac{m}{s},A1=2600m{m}^2$ and $A2=650m{m}^2-$ Determine the reaction forces on

the curve with the passage of the flow. Answer: $Fx=68\mathrm{.}4N$;$Fy=267\mathrm{.}8N.$
