Question
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 and (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.
