If 73' (22.3 m) of pipe is to be jacketed with 36" (91.4 cm) roll sheet metal sections with a 2" (5.1 cm) butt overlap, how many whole sections will be required?
a. 23
b. 24
c. 26
d. 28
c. 26
Pipe length:
73' x 12" = 876" (2,225 cm)
Jacket Exposed Length:
36" – 2" = 34" (86.4 cm)
Number of Sections:
876" ÷ 34"/section = 25.8 = 26 sections (round up)
or
2,225 cm ÷ 86.4 cm/section = 25.8 = 26 sections (round up)
