Other things being equal, hotter air is less dense than cooler air and will thus rise through cooler air. Air is a mixture of gases and the calculations always simplify, to a greater or lesser extent, the properties of the mixture. ĭepending on the measuring instruments used, different sets of equations for the calculation of the density of air can be applied. Pure liquid water is 1,000 kg/m 3 (62 lb/cu ft).Īir density is a property used in many branches of science, engineering, and industry, including aeronautics gravimetric analysis the air-conditioning industry atmospheric research and meteorology agricultural engineering (modeling and tracking of Soil-Vegetation-Atmosphere-Transfer (SVAT) models) and the engineering community that deals with compressed air.

At 101.325 kPa (abs) and 15 ☌ (59 ☏), air has a density of approximately 1.225 kg/m 3 (0.0765 lb/cu ft), which is about 1⁄ 800 that of water, according to the International Standard Atmosphere (ISA). The specific volume of water depends on temperature as shown below: Heavy. The output specific volume is given as cm /g, ft /lb, gal (US liq)/lb and ft. At 101.325 kPa (abs) and 20 ☌ (68 ☏), air has a density of approximately 1.204 kg/m 3 (0.0752 lb/cu ft), according to the International Standard Atmosphere (ISA). The calculator below can be used to calculate the liquid water specific volume at given temperatures. The output density is given as kg/m, lb/ft, lb/gal (US liq) and sl/ft. Density is mass divided by volume (m/v), and water was used as the basis for establishing the metric unit of mass, which means a cubic centimeter (1cm 3) of water weighs one gram (1g). It's no coincidence that water has a density of 1. In Imperial or US customary measurement system, the density is equal to 26.469 pound per cubic foot lb/ft³, or. The calculator below can be used to calculate the ammonia gas density and specific weight at given temperatures and atmospheric pressure. The density of water is most given as 1 g/cm3, but below is the density of water with different units. density of methane, liquid is equal to 424 kg/m³ at -164☌ (-263.2☏ or 109.15K) at standard atmospheric pressure. It also changes with variations in atmospheric pressure, temperature and humidity. Search: Precision: Methane, liquid weighs 0.424 gram per cubic centimeter or 424 kilogram per cubic meter, i.e. Air density, like air pressure, decreases with increasing altitude. The density of air or atmospheric density, denoted ρ, is the mass per unit volume of Earth's atmosphere. Mass per unit volume of the Earth's atmosphere
