Figure 121: Flow Domain

Material Properties	Geometry	Boundary Conditions
Density: 997 kg/m³ Viscosity: 8.899 X 10^-4 kg/m-s	Radius of the pipe = 14 mm Radius of the pipe bend = 125 mm	Velocity profile at inlet with an average velocity of 1.42 m/s

Material Properties

Geometry

Boundary Conditions

Density: 997 kg/m³

Viscosity: 8.899 X 10^-4 kg/m-s

Radius of the pipe = 14 mm

Radius of the pipe bend = 125 mm

Velocity profile at inlet with an average velocity of 1.42 m/s

Analysis Assumptions and Modeling Notes

The flow is steady. Symmetry condition is applied on one side of the pipe.
