I have experienced the same problem. I ran the numbers on your tank in my spreadsheet. Jet mixing works best when the jet Reynolds Number and tank Reynolds Number are both turbulent. The best I could do was the tank was laminar and the jet was transitional. It doesn't look good for jet mixing. It's too far removed from the design basis. Have you considered a mechanical agitator?
Good luck,

To a ChE, the glass is always full - 1/2 air and 1/2 water.
I didnt considered agitator.in my study, jet Reynolds Number is approximately 2000.based on your experiencs, which one equation can I apply for solution of this problem, do you have applicabe document to help me?
Good luck,

Yes, I got a jet Reynolds Number of 1480 for a 1.61 inch nozzle outlet diameter. Our design guidelines on jet Reynolds Number are > 10,000, if possible. No, my spreadsheet/technology belongs to the company and their fluid flow technologist. The reference given is Mixing in the Process Industries 2nd Ed. by Harnby, Edwards, and Nienow.
