A reducing elbow in a horizontal pipe is used to deflect water flow by an angle 0 = 56° from the flow direction while accelerating it. The elbow discharges water into the atmosphere. The cross-sectional area of the elbow is A1=136 cm² at the inlet and A2=12 cm² at the exit. The elevation difference between the centers of the exit and the inlet is H=44 cm. The mass of the elbow and the water in it is 70 kg. Disregarding frictional effects, determine the y-component of the anchoring force needed to hold the elbow in place, in kN. Give your answer to 2 decimal places. Take the momentum-flux correction factor to be kg 1.03 at both the inlet and outlet. Take the density of water to be 1000- and m3 the mass flow rate to be 50*8. Include "+" or "_" sign in your answer. "+" y-direction points upward; "-" y- direction points downward. (Hint: the gauge pressure at the elbow inlet is NOT zero.
