Referring to an ultrasound device (sonica 2200 soltec, ultrasound frequency:40 kHz) we know the efficiency of cavitation of 300 mL water placed in 1 becker inside the sonication bath (3 L volume). The device has two specific position for 300 mL beckers. Hence we can assume same efficiency inside a second Becker, i.e: treating 600 mL instead treating 300 mL. Hence, the ratio energy consumed:volume treated would be half. Could we approximately assume the same applied to 3 L solution placed directly in the sonication bath, or the cavitation efficiency would be significantly reduced?
If I understand your question you want to have a ultrasonicated volume within a bath. The ultrasound field is not uniform over volume it is designed for utility cleaning. Your use of the bash for cavitation will need to be graded on the results of your beaker position in the bath. A short discussion from Heilsher details this in a more complete fashion.

No. If you shine a flashlight on a wall, are parts of the wall better illuminated than others? Same thing with ultrasound ensonification.
