Question:
Repeat Prob. 13??22 for the case of another (identical) elbow attached to the existing elbow so that the fluid makes a U-turn.
Repeat Prob.
A 90? elbow in a horizontal pipe is used to direct water flow upward at a rate of 40 kg/s. The diameter of the entire elbow is 10 cm. The elbow discharges water into the atmosphere, and thus the pressure at the exit is the local atmospheric pressure. The elevation difference between the centers of the exit and the inlet of the elbow is 50 cm. The weight of the elbow and the water in it is considered to be negligible. Determine
(a) The gage pressure at the center of the inlet of the elbow
(b) The anchoring force needed to hold the elbow in place. Take the momentum-flux correction factor to be 1.03 at both the inlet and the outlet.
