What is the structural relationship between the throat and the nozzle in a single venturi tube that can achieve an ideal gas extraction volume ratio?
Thread Content
A single-venturi negative pressure device with water spraying is required; the throat diameter should be 5 mm, the length 10 mm, with the converging and diverging sections following standard specifications. I don’t know now how to determine the nozzle diameter and spray distance; after checking some information, the range of values for these parameters do not overlap. The area ratio ranges from 3.5 to 4, as well as from 4 to 10. The value of the spraying distance also varies. I don’t know how to do it. Does anyone here have any experience or information in this area that they could share with me? Thank you! The email address is 2528235517@qq.com
By the way, how is the jet diffusion angle calculated?
