surface, that is, on the mixing technique, on the bubble dimensions, and on the 

 propulsor length. Therefore, at present only experimental observations can 

 suggest more exact ideas about the expansion law. 



(j) No water evaporation is considered. 



3.3 Basic Equations 



With reference to Figs. (5) and (6), when the Bernoulli equation is applied 

 between sections (co) and (i) there results 



Pi - Pa + gPH^i + gPHHp +— (V„2_V.2) - gpj^AH^

(3) 



Symbols are listed at the end of the paper; the z- coordinate is positive down- 

 wards. By means of dimensionless parameters, Eq. (3) can be written as:
