The density of air depends on many factors and can vary in different places. It mainly changes with temperature, relative humidity, pressure and hence with altitude (take a look on the air density table below). The air pressure can be related to the weight of the air over a given location...
As an example of howwater densitychanges with temperature, at 1 atm pressure water has an estimated density of 983.854 kg/m3at -30 °C, 999.9720 kg/m3at 4 °C and only 958.4 kg/m3at 100 °C (boiling temperature at sea-level). Thedensity of air at sea levelis approximately 1.293 kg...
Densities and molecular weights of common gases like acetylene, air, methane, nitrogen, oxygen and others. Helium - Density and Specific Weight vs. Temperature and Pressure Online calculator, figures and tables showing density and specific weight of helium, He, at varying temperature and pressure ...
🙋 If you want to reach the sky, you may also be interested in using our air density calculator. What is the density of water? The density of water (or any other substance) is the ratio of its mass, m, to its volume, V. We usually denote density using the symbol ρ, so the ...
temperatures, another common value is NTP, which stands for normal temperature and pressure. NTP is defined as air at 20 degrees C (293.15 K, 68 degrees F) and 1 atm (101.325 kN/m2, 101.325 kPa) of pressure. The average density of air at NTP is 1.204 kg/m3(0.075 pounds per cubic ...

Suppose a 1 m3cube of ice is transported without melting from Mount Everest to a location at sea level. The atmospheric pressures at the peak of Mount Everest and at sea level are 0.31 atm and 1 atm, respectively. Determine the change in the volume of ice (ΔV). Take the compressibility...
How may the ideal gas law be used to calculate the density of air at sea level? Ideal Gas Law The equation of the ideal gas show that pressure (P) is proportional to the number of moles (n) times the temperature (T), divided by the volume (V): ...
The effects of dissolved air and of natural isotopic distributions on the density of water have been determined at 1 atm by using a magnetic float densimeter. FJ Millero,RT Emmet 被引量: 0发表: 1975年 Kinetic isotopic fractionation during air‐water gas transfer of O2, N2, CH4, and H2 We...
If you're in internet range, you don't need to supply any data. If you're out of internet range, all you need to supply is the outside air temperature. Great tool for pilots, drag racers, engine tuners, or anyone who needs to conveniently find their Air Density, Density Altitude, ...
