Excel or app to calculate air vents in stainless steel tanks

I would like to make an app or a spreadsheet in Excel to calculate the diameter of the ventilation of stainless steel tanks for sanitary use or food processes. This program must have as input information the volume of the tank, the initial temperature, the final temperature, the time of temperature change, the safety factor, and the air velocity in the pipe, as shown in the image. If it is possible to add more information to the calculation to be more precise I would like it.
