      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 ?
       
      Regards,

      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.
