$2-47.$ The vertical pipe segment has an inner diameter of

$100$ mm and is capped at its end and suspended from the

horizontal pipe as shown. If it is filled with water and

the pressure at $A$ is $80$ kPa $,$ determine the resultant force

that must be resisted by the bolts at $B$ in order to hold the

flanges together. Neglect the weight of the pipe but not the

water within it$.$
