3. Water is flowing through a 15 cm diameter pipe that consists of a 3 m long
vertical and 2 m long horizontal section with a 90° elbow at the exit to force
the water to be discharged downward, as shown in the figure below, in the
vertical direction. Water discharges to atmospheric air at a velocity of 7 m/s,
and the mass of the pipe section when filled with water is 15 kgm per meter
length. Determine the moment acting at the intersection of the vertical and
horizontal sections of the pipe (point A). What would your answer be if the
flow were discharged upward instead of downward?
