SUMMARY
The discussion focuses on calculating the shear rate in a bent pipe with varying bend radii, specifically a 90° bend where the radius of curvature is 50 mm and the pipe diameter is 40 mm. It is established that the shear rate at the wall is not uniform around the circumference of the curved sections. For large radius of curvature compared to the pipe diameter, a simplified approach can be used, treating the flow as if it were in a straight pipe. A ratio of 10:1 between the radius of curvature and pipe diameter is suggested to determine if the shear rate can be considered negligible.
