About blocking of mechanical seals
The exit section when blocked is a critical section. For a certain ratio, it corresponds to the maximum flow rate possible. Subsonic speed has a constant maximum inlet Mach number, while supersonic speed has a constant minimum inlet Mach number, and blockage occurs at this time.
This is true for the isentropic flow in the tapered nozzle, but also for the converging nozzle. When blockage occurs, the specific mass of the throat section reaches its maximum value, and the throat section is a critical section. 332.html,
