A marine terminal for unloading bulk wheat from a ship is equipped with a vertical pipe with a nozzle at A which sucks wheat up the pipe and transfers it to the storage building. Calculate the x$-$ and y$-$components of the force R required to change the momentum of the flowing mass in rounding the bend. Identify all forces applied externally to the bend and mass within it$.$ Air flows through the $350$ mm diameter pipe at the rate of $16$ Mg per hour under a vacuum of $230$ mm of mercury $($ p $=30$ kPa gage$)$ and carries with it $135$ Mg of wheat per hour at a speed of $40$ m$/$s
