- A de Laval nozzle will only choke at the throat if the pressure and mass flow through the nozzle is sufficient to reach sonic speeds, otherwise no supersonic flow is achieved, and it will act as a Venturi tube; this requires the entry pressure to the nozzle to be significantly above ambient at all times ( equivalently, the stagnation pressure of the jet must be above ambient ).
- It's difficult to find entry pressure in a sentence. 用entry pressure造句挺難的
