Engineering Methodology

How to Calculate 4" Steel Pipe Volume

Exact cylinder geometry calculations based on ASME B36.10M inside diameter tolerances.

Step 1

Determine Inside Radius ($r$)

Divide ASME inside diameter by 2:

r = 4.026" / 2 = 2.0130"

Step 2

Compute Flow Area ($A$)

Calculate circular internal cross-sectional area:

A = \pi \times (2.0130)^2 = 12.7303 sq in

Step 3

Calculate Linear Foot Volume

Multiply cross-sectional area by 12 inches (1 linear foot):

V_linear = 12.7303 \times 12 = 152.763 cu in/ft

Step 4

Convert to US Gallons & Weight

Divide cubic inches by 231 (cubic inches in 1 US Gallon):

Gal/Ft = 152.763 / 231 = 0.6613 Gal/Ft
