Dear All,

I try to size an instrument/ utilty air buffer drum. I know how I can find the totla volume of vessel, but I don't know how I can fix the height and diameter of vessel.

Is it any rule of thumb or criteria availabel for such a sizing?


Thanks

Dear Breizh,

Thank you for your fast reply. Could you please advise me what's base for that figure.Is it based on minimum vessel capital cost or something else?

Thanks

Dear Breizh,

For my case I changed L/D ratio from 1 to 7 and estimated the weight for each L/D ratio.With higher L/D ratio vessel need lower thickness compare to lower L/D ratio.For my case L/D ratio of 5 give me lower vessel weight, but the vessel hight will be around 7.8 m. Can I select this dimension?There is no any limitation on height or dimeter?

Thanks
