The density of air or atmospheric density, denoted ρ, is the mass per unit volume of Earth's atmosphere. Air density, like air pressure, decreases with increasing altitude. It also changes with variation in atmospheric pressure, temperature and humidity. At 101.325 kPa (abs) and 20 °C (68 °F), air has a density of approximately 1.204 kg/m (0.0752 lb/cu ft), according to the International Standard Atmosphere (ISA). At 101.325 kPa (abs) and 15 °C (59 °F), air has a density of approx… WebIn most duct calculations with air, one can use a constant atmospheric air density value of 0.075 lbm/ft^3 because temperature variations are limited to +/- 40 from 80 and the in-℉ ℉ duct pressure is close to atmosphere—even if it varies by an inch of water (keep in mind that atmospheric pressure is 34ft x12in/ft=408 inches of water).
