How do you find the density of air with temperature?
Calculation of Air Density
- R is the Gas constant = 287.05 J/kg-K.
- T is the temperature in K. Air is assumed to be at 20°C so, T = (20 + 273.15)
- P is standard pressure:
- Z = Elevation above sea level (m)

What is STP density?
The value for the density of air at STP (Standard Temperature and Pressure) depends on the definition of STP. The ISA or International Standard Atmosphere states the density of air is 1.225 kg/m3 at sea level and 15 degrees C. The IUPAC uses an air density of 1.2754 kg/m3 at 0 degrees C and 100 kPa for dry air.
What is the viscosity of air at 20 degrees Celsius?
Kinematic viscosity of air at 20°C is given to be 1.6 × 10-5 m2/s.
What should the density of air be in G L?
1.29 grams per liter
The Density of Air Values The density of dry air is 1.29 grams per liter (0.07967 pounds per cubic foot) at 32 degrees Fahrenheit (0 degrees Celsius) at average sea-level barometric pressure (29.92 inches of mercury or 760 millimeters).
How do you find the density on a calculator?
The Density Calculator uses the formula p=m/V, or density (p) is equal to mass (m) divided by volume (V). The calculator can use any two of the values to calculate the third. Density is defined as mass per unit volume.
What is the density of air at 20 degrees C?
For ordinary 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/m 2, 101.325 kPa) of pressure. The average density of air at NTP is 1.204 kg/m 3 (0.075 pounds per cubic foot).
How is air density and specific weight related?
Air density and specific weight at atmospheric pressure: Air density at ambient temperature and pressure: Air density at varying pressure and temperature: Air density at gas-liquid equilibrium pressure: Air thermal expansion coefficient at atmospheric pressure:
What is the density of air at NTP?
The average density of air at NTP is 1.204 kg/m 3 (0.075 pounds per cubic foot). If you need to calculate the density of dry air, you can apply the ideal gas law. This law expresses density as a function of temperature and pressure.
What is the density of air at STP?
