Design Properties—Schedule 80 PVC

D = outside diameter of pipe, inches
d = inside diameter of pipe, inches (Average based on mean wall)
t = average wall thickness, inches
Ao = D x pi/12 = outside pipe surface, sq. ft per ft. length
A1 = d x pi/12 = inside surface, sq. ft. per ft. length
A = (D2 - d2) x pi/4 = cross-sectional plastic area, sq.in
Af = d2 x pi/4 = cross sectional flow area, sq.in.
W pvc = .632 x A = weight of pipe, lb. per ft. length
W cpvc = .705 x A = weight of pipe, lb. per ft. length
Ww = 0.433 Af = weight of water filling, lb. Per ft. length
rg = √ I

A
= √ D2 + d2

4
= radius of gyration, inches
I = Arg2 = .0491 (D4-d4) = moment of inertia, inches fourth
Z = 2I/D = 0.0982 x (D4-D4)/D = section modulus, inches cube
Wwfp = Wpvc  (or Wcpvc) + Ww = weight of water filled pipe, lb. Per ft. length
Capacity
VG = V x 0.004329 = Volume capacity, gallons per ft. length
V = 0.7854 x d2 x12 = Volume capacity, cubic inches per ft. length
