The 10-foot row lists 1/2 inch = 174 CFH. What size is required for that water-heater branch under the longest-length method?

1/2 inch is adequate, because 40 CFH is less than 57 CFH on the 80-foot row 3/8 inch, because you may use the 10-foot row for this short branch 1 inch, because all branches must be 1 inch on an 80-foot system The branch cannot be installed
