The average slope of a characteristic line between two points, such as points twelve and thirteen in fluid dynamics, refers to the average rate of change of a certain property or variable along the path defined by the characteristic line as you move from point twelve to point thirteen. This property or variable can vary depending on the context of the problem and the specific characteristics of the flow.
- Average slope of characteristic line between points twelve and thirteen
- Angle between velocity to the below velocity at point twelve (𝜃12) in rad
- Angle between velocity to the below velocity at point thirteen (𝜃13) in rad
