Notes: 1) All pipe sizes are based on the following: copper pipe (Type L), 14.7 psia, 70° F
2) The minimum pipe size must be maintained for the total length of the inlet pipe.
Use next larger size pipe in the event the minimum is not available.
3) When determining the total pipe length, add all the straight lengths of pipe
together in addition to the number of elbows times the eff ective pipe length for
that pipe size. (See Table 2.2 and example on page 2-3.)
