Question: The pressure pipe elbow with 30 degree orientation in the vertical plane is 60 cm in diameter. The flow rate of the current passing through the elbow is 1 m3/s. In the section at the lower end (1) of the elbow, the pressure is 70 kPa and the ground elevation is 30 m, and in the section at the upper end (2), the ground elevation is 31 m. Considering that the fluid is water (pwater=1000 kg/m3), frictionless and incompressible,

![Question: The pressure pipe elbow with 30 degree orientation in the vertical plane is 60 cm in
diameter. The flow rate of the current passing through the elbow is 1 m3/s. In the section at
the lower end (1) of the elbow, the pressure is 70 kPa and the ground elevation is 30 m, and in
the section at the upper end (2), the ground elevation is 31 m. Considering that the fluid is
water (pwater=1000 kg/m3), frictionless and incompressible,
a) Find the velocities in sections (1) and (2) and the pressure in section (2).
b) The weight of the pipe at the elbow is 1400 N. If the length between the sections is 1.2 m,
calculate the force that must be applied in the vertical direction to keep the elbow fixed,
taking into account the mass of water at the elbow.
