I have a question regarding the pressure equalization holes in the return tank
Thread Content
In the liquid inlet pipe of my reflux tank, there should be two pressure equalization holes with a diameter of 50 mm (as specified in the design drawings). During maintenance, it was found that such holes were not present on that pipe; therefore, 10 holes with a diameter of 10 mm were drilled using an impact drill. After operations started, the tower pressure experienced significant fluctuations. I would like to know how to determine the diameter of the pressure equalization holes Furthermore, the temperature of the cooler at the top of that tower often changes suddenly, ranging from 50 to 77 degrees. Could this be related to the fact that the pressure equalization holes are not open?

Has the resistance at those 10 small holes increased? This is something that needs to be taken into consideration
