Question: Water flowing in a positive x-direction passes through a 90 elbow in a 6-inch-diameter pipeline and heads in a positive y-direction with a flow rate

Water flowing in a positive x-direction passes through a 90° elbow in a 6-inch-diameter pipeline and heads in a positive y-direction with a flow rate of 3.05 ft3/sec. Compute the magnitude and direction of the force exerted by the elbow. The pressure upstream of the elbow is 15.l psi; just downstream it is 14.8 psi.
