The slope of a left-running Mach wave characteristic between points two and three represents the rate of change in the Mach number (M) per unit change in position (typically distance) along the characteristic path from point two to point three. This slope describes how the Mach number varies as one moves along the path of the left-running Mach wave characteristic.
- The slope of left running Mach wave characteristic between points two and three
- Angle between velocity to the below velocity at point two (𝜃2) in rad
- Angle between velocity to the below velocity at point three (𝜃3) in rad
- Angle between above streamline to the velocity at point two (𝜇2) in rad
- Angle between velocity to the below horizontal at point three (𝜇3) in rad
