Engineering Formula

How to Calculate 2" PVC Pipe Volume Manually

Step-by-step mathematical demonstration using cylinder geometric principles and ASTM D1785 specifications.

Step 1

Determine the Internal Radius (r)

Nominal size is 2", but true inner diameter is 1.939 inches.

r = ID / 2 = 1.939 / 2 = 0.9695"

Step 2

Calculate Cross-Sectional Area (A)

Compute circular cross-section area using $A = \pi \times r^2$:

A = \pi \times (0.9695)^2 = 2.9529 sq in

Step 3

Calculate Linear Foot Volume

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

V_linear = 2.9529 \times 12 = 35.435 cu in/ft

Step 4

Convert to US Gallons & Liters

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

Gallons/Ft = 35.435 / 231 = 0.1534 Gal/Ft

2 Questions Answered

Q1 How many gallons does 100 feet of 2" Schedule 80 PVC pipe hold?

A 100-foot run of 2-inch Schedule 80 PVC pipe holds 15.34 US Gallons (58.07 Liters) of water.

Q2 Why does 2" Schedule 80 hold less volume than 2" Schedule 40?

Both have identical outer diameters (2.375"), but Schedule 80 has a much thicker wall (0.218" vs 0.154"), reducing the inner diameter from 2.067" down to 1.939".
