True or False: If the impeller is below the critical submersion depth, not only is the negative pressure area blocked by a water film, but the water jump phenomenon is also significantly weakened; in some cases, no water jump occurs at all, and thus no mixing action can take place ( ).
If the impeller is below the critical submersion depth, not only is the negative pressure area blocked by a water film, but the water jump is also significantly weakened or even fails to form, preventing any stirring action (X).
If the impeller is below the critical submersion depth, not only is the negative pressure area blocked by a water film, but the water jump is also significantly weakened or even fails to occur, preventing any mixing action (Wrong).
If the impeller is below the critical submersion depth, not only is the negative pressure zone blocked by a water film, but the water jump is also significantly weakened or even fails to form, preventing any stirring action (Incorrect).
If the impeller is below the critical submersion depth, not only is the negative pressure zone blocked by a water film, but the water jump is also significantly weakened or even fails to occur, resulting in no mixing action (incorrect).
