A reducing elbow is used to deflect water flow at a rate of 30 kg/s in a horizontal pipe upward by an angle 0 = 45° from the flow direction while accelerating it. The elbow discharges water into the atmosphere. The cross-sectional area of the elbow is 150 cm² at the inlet and 25 cm² at the exit. The elevation difference between the centres of the exit and the inlet is 40 cm. The mass of the elbow and the water in it is 50 kg. a) Determine the gauge pressure at inlet. b) Determine the anchoring force needed to hold the elbow place. Water 150 cm² 25 cm² 45° 40 cm
