3.3.6. Water flowing in a positive x-direction passes through a 90° elbowin a 6-in.-diameter pipeline and heads in a positive y-direction (FigureP3.3.6). If the flow rate is 3.05 ft³/s, compute

the magnitude and directionof the reaction force (F). The pressure upstream of the elbow is 15.1 psi;just downstream it is 14.8 psi.
