Question

A reducing elbow is used to deflect water flow at a rate of 14 kg/s in a horizontal pipe upward 30° while accelerating it (Figure 6). The elbow discharges water into the atmosphere. The cross-sectional area of the elbow is 113 cm^2 at the inlet and 7 cm^2 at the outlet. The elevation difference between the center s of the outlet and the inlet is 30 cm. The weight of the elbow and the water in it is considered to be negligible. Determine (i) the gage pressure at the center of the inlet of the elbow and ii) the anchoring force needed to hold the elbow in place.

Step 1

We can use the equation of continuity, which states that the mass flow rate is constant throughout the pipe. This gives us: V1 = (14 kg/s) / (113 cm^2 * 1 kg/m^3) = 0.124 m/s V2 = (14 kg/s) / (7 cm^2 * 1 kg/m^3) = 2 m/s Show more…
