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 … See more Other things being equal, hotter air is less dense than cooler air and will thus rise through cooler air. This can be seen by using the ideal gas law as an approximation. See more Troposphere To calculate the density of air as a function of altitude, one requires additional parameters. For the troposphere, the lowest part (~10 … See more • Conversions of density units ρ by Sengpielaudio • Air density and density altitude calculations and by Richard Shelquist See more The addition of water vapor to air (making the air humid) reduces the density of the air, which may at first appear counter-intuitive. This occurs because the molar mass of water vapor (18 g/mol) is less than the molar mass of dry air (around 29 g/mol). For any … See more • Air • Atmospheric drag • Lighter than air • Density See more WebThe density of water is about 800 times that of air, but its bulk modulus is about 15 000 times that of air; consequently the speed of sound in water (about 1450 m s −1) is much …

WebMar 15, 2024 · Since environment pressure decreases with elevated altitude, diesel engines that operate in high-altitude regions commonly experience low charge density that result in poor mixture preparation and decreased combustion efficiency. Low engine efficiency, high fuel consumption, and high emissions are generally observed.

In general, density can be changed by changing either the pressure or the temperature. Increasing the pressure always increases the density of a material. Increasing the temperature generally decreases the density, but there are notable exceptions to this generalization. For example, the density of water increases between its melting point at 0 °C and 4 °C; similar behavior is observed in silicon at low temperatures.
