*Table includes losses for four 90 degree bends and two (2) end fittings. Tubing runs with larger numbers of bends and/or fitting shall be increased by an equivalent length of
tubing according to the following formula:
L = 1.3 (n) L = is the additional length (ft.) of tubing to be added to actual run. n = is the number of additional fittings and/or bends.
