A reversing elbow is used to induce a 180 U-turn of water before it is discharged to the atmosphere. The mass flow rate of water is 25 kg/s. The cross-sectional area of the elbow is 0.02 m? at the inlet and 0.001 m? at the outlet. The elevation difference between the centers of the inlet and the outlet is 90 cm. The mass of steel elbow is 90 kg while the volume of elbow is 0.35 m. Determine the gauge pressure at the center of inlet of the elbow and the anchoring force needed to hold the elbow in place. Assume B = 1.04. P2 P1 V1
