Question 3 (12 marks) A reducing elbow is used to deflect water flow at a rate of 25 kg/s in a horizontal pipe upward by an angle 0=60° from the flow direction while accelerating it. The elbow discharges water into the atmosphere. The diameter of the elbow at the inlet isl9 cm and at the exit 2 cm. The elevation difference between the centers of the exit and the inlet is 36 cm. The mass of the elbow and the water in it is 45 kg. Determine the anchoring force needed to hold the elbow in place. 2-cm-diameter 9-cm-diameter 36 cm Water
