Step-by-step mathematical demonstration using cylinder geometric principles and ASTM B88 specifications.
Nominal size is 2", but true inner diameter is 1.985 inches.
r = ID / 2 = 1.985 / 2 = 0.9925" Compute circular cross-section area using $A = \pi \times r^2$:
A = \pi \times (0.9925)^2 = 3.0946 sq in Multiply cross-sectional area by 12 inches (1 linear foot):
V_linear = 3.0946 \times 12 = 37.136 cu in/ft Divide cubic inches by 231 (cubic inches in 1 US Gallon):
Gallons/Ft = 37.136 / 231 = 0.1607 Gal/Ft Physical dimensions, pressure thresholds, and hydraulic velocity limits.
Primary Use Case: Large commercial water entry manifolds, high-rise residential risers, and central heating and cooling plant distribution.
