Fluid elbow momentum conservation

Описание к видео Fluid elbow momentum conservation

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 . The elbow discharges water into the atmosphere. The cross-sectional area of the elbow
is 113 cm2 at the inlet and 7 cm2 at the outlet. The elevation difference
between the centers 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 (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.
