I challenge the assertion that "ram pressure" can only exist during supersonic flow. I would define "ram pressure" to be equivalent to the dynamic pressure of the flow, equal to (1/2) x (density) x (velocity)^2 in the incompressible regime, and defined by the total pressure/static pressure compressible relation in the compressible regime (Ma > 0.3). - Fyre4ce |
