NPS (½–60)
OD (in)
Standard OD auto-fills; override for odd spec pipe.

Linear footage (ft)
Target DFT (mils)
Volume solids (%)
If unknown, leave 100% for theoretical coverage.
Assumptions
Theoretical spread rate: 1 gal covers 1604 ft² at 1 mil DFT for 100% solids. Adjust solids for your product.

Notes
Area = (π × OD / 12) × Length. Gallons = Area × mils ÷ (CoverageConstant × SolidsFraction). This is a theoretical estimate. Confirm with product TDS and client requirements.
