Explanation & Application

The tables provide the internal volume of water (or other fluid) contained within a pipe per linear foot. This is critical for:

  • System filling calculations
  • Thermal expansion estimates
  • Pump sizing and system commissioning

How to Use: To find the total water volume for a pipe run, multiply the value from the table (gal/ft) by the total pipe length in feet.

Calculation Example: For a 50 ft run of 3/4" Schedule 40 steel pipe: Volume=0.0277 galft×50 ft=1.385 gallons\text{Volume} = 0.0277\ \frac{\text{gal}}{\text{ft}} \times 50\ \text{ft} = 1.385\ \text{gallons}

Key Definitions:

  • Nominal Pipe Size (NPS): A dimensionless designation of pipe size, related to but not equal to the actual physical diameter.
  • Schedule: Indicates the wall thickness of the pipe. Higher schedule numbers have thicker walls, resulting in a smaller internal bore and less water content per foot.
