| Step No. 4 | Total all pipe lengths.
Refer to the Volume Chart. Chose a given pipe size and multiply the ml per
foot by the total length of all the pipe. If the sum falls within the
acceptable range noted in Tank Chart, that pipe size is acceptable. If the
calculated volume is too large, recalculate the volume using the ml per
foot of a smaller pipe size. See Figure 3-21.
Add section A-B = 0'-6" + 5' + 14' + 2' + 0'-6" = 22' (.2 + 1.5 + 4.3 + .6 + .2 = 6.8 m) Add section B-C = 1'-6" (.5 m) Add section C-D = 1' (.3 m) Add section D-E = 2' (.6 m) Add section E-F = 0'-6" (.2 m) Add section F-L = 3' + 2' + 2' = 7' (2.1 m) Add section B-G = 0'-6" (.2 m) Add section C-H = 2' + 2' = 4' (.6 + .6 = 1.2 m) Add section D-I = 2' + 2' = 4' (.6 + .6 = 1.2 m) Add section E-J = 0'-6" + 0'-6" = 1' (.3 m) Add section F-K = 2' + 2' = 4' (.6 + .6 = 1.2 m) Total length of all pipe = 47'-6" (14.5 m) |
Refer to Volume Chart. The pipe size chosen is 3/8 inch. The volume per foot of 3.8 in. pipe is 37.5 ml. Multiply 37.5 by the total pipe length of 47.5 ft.
37.5 ml. x 47.5 ft. = 1781 ml total volume
The maximum volume allowed for a PCL-300 is 1910 ml, therefore, 3/8 in. pipe is acceptable for their system.
