Determination of the overflow opening size for atmospheric pressure rectangular tanks
Thread Content
Currently, the medium inside the atmospheric-pressure rectangular tank is an alkaline solution. The tank is equipped with an overflow port to maintain atmospheric pressure. Since an electric heating system is installed in the tank, the temperature of the alkaline solution remains around 80°C. How should the size of the overflow port be determined in order to maintain atmospheric pressure?
Make it bigger then; it’s going to overflow anyway.
What is the size of the inlet pipe? In addition to overflow, it should also serve a breathing function; if it is used solely for exhalation, a pipe diameter of DN100 or DN80 for overflow should be sufficient
