Step-by-step mathematical demonstration using cylinder geometric principles and ASTM D1785 specifications.
Nominal size is 1", but true inner diameter is 0.957 inches.
r = ID / 2 = 0.957 / 2 = 0.4785" Compute circular cross-section area using $A = \pi \times r^2$:
A = \pi \times (0.4785)^2 = 0.7193 sq in Multiply cross-sectional area by 12 inches (1 linear foot):
V_linear = 0.7193 \times 12 = 8.632 cu in/ft Divide cubic inches by 231 (cubic inches in 1 US Gallon):
Gallons/Ft = 8.632 / 231 = 0.0374 Gal/Ft Physical dimensions, pressure thresholds, and hydraulic velocity limits.
Primary Use Case: Heavy-duty industrial water processing, commercial carwash pressure piping, and aggressive fluid handling.
