Question

10. A 45° reducing elbow can be found in domestic water piping systems. Water flows into the elbow with a velocity of 0.82 m/s and is deflected through an angle

of 45°. The inlet diameter is 2.5cm, and the outlet diameter is 1.2cm. The inlet and outlet gage pressures are160kPa and 158 kPa, respectively. If the elbow is located in a horizontal plane, determine the restraining forces Fx and Fy (in Newtons) Take water density to be 1000 kg/m³. (Hint: Watch video “Chapter 5-Reducin elbow.mp4")
