i. (20 points) A 90° elbow in a horizontal pipe is used to direct water flow upward at a rate of 30 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 40 cm. The weight of the elbow and the water in itis considered to be negligible.2Determine (a) the gage pressure at the40 cm center of the inlet of the elbow and (b) the anchoring force needed to hold the elbow in place . Take correction factor to be 1.03 at both the the momentum-flux at both inlet and the outlet.
