Hi,
I am sizing a KO drum and I'm facing trouble achieving the recommended L/D ratio. One issue, which I, myself, can manage, is that I yet have not used the standard vessel diameter. The second issue is that the height I obtained for the liquid gravity section is too low (<< 1 ft). My supervisor mentioned there's a standard guideline but couldn't recall the exact value (maybe 1 ft or 2 ft). I couldn't find the information in reference books. I need help to determine the length and resolve these issues. Any insights or suggestions would be appreciated.
