The intent of this feasibility study was to generate data of sufficient reliability to enable researchers to draw general conclusions regarding the efficacy of siphons for degassing water and to identify the most important variables for the process. We believe the data generated by this brief study have achieved these goals but caution against using the data for designing siphons to achieve a specific level of degassing efficiency. For this purpose, we strongly recommend a more elaborate and carefully conducted series of tests. To provide a means of predicting the degassing efficiency of siphons of a given design, a general formula should be derived. Such a formula might take into account the following factors:
The empirical determination of the accurate degassing efficiency of various devices for increasing turbulence was beyond the scope of this study. Until such studies are completed, a general formula for use in designing prototype siphons cannot be derived.
