    Well, it depends……
    What kind of coke are you making ?
    What is your current cutting water pressure ?
    What is your current water flow ?
    How fast do you want to cut the coke ?
    What cycles are you running ? 24, 18 hr ?
    Do you plan on running shorter cycles with the larger drums ?
    What cutting tool do you currently have ?
    How efficient is your current cutting operation ?

    some designer take like thumb rule between 110-130 psig for each feet of drum diameter (fuel grade)

    125 psi/ft diameter seems to be at least one rule of thumb that I keep running into.  I read this in some literature on Norm Lieberman and other places.
