Conversion from seconds to hours (ASTM method uses 60 to convert in minutes)
Water vapor in gas stream, proportion by volume; assume 2%
Cross sectional area of dilution tunnel, ft
Standard absolute temperature, 528 °R
Absolute average gas static pressure in dilution tunnel, = P
Absolute average gas temperature in the dilution tunnel, °R; (°R = °F + 460)
