Question

Water is flowing into and discharging from a pipe U-section as shown in the figure below. At flange (1), the total absolute pressure is 200 kPa, and 55 kg/s flows into the pipe. At flange (2), the total pressure

is 150 kPa. At point (3), water discharge to atmosphere is at 100 kPa. Determine the total x- and z-

forces at the two flanges connecting the pipe. Discuss the significance of gravity force for this problem.

Take the momentum-flux correction factor to be 1.0 throughout the pipes.

a) Make a total mass balance and find the flow rate at Point 3. (10 points)

Explain whether do you consider st.st. or unst.st for this? Why?​
