What is the average density of air?

1.225 kg/m³
For dry air, its density at sea level at 59 °F (15 °C) and 14.7 psi (1013.25 hPa) (mean sea-level pressure), is approximately 0.0765 lb/cu ft (1.225 kg/m³) .

#### What is the density of air at 50 C and 300 kPa?

SOLVED:Find the density of air at 50 C and 300 kPa 1.244 kg/m” 2.345 kg/m’ 3.24 kg/m’ 1024 kg/m’ Refer a Friend.

How do you calculate air density?

Density is a measure of mass. The formula for density is d = m/v, where d is the density, m is the mass, and v is the volume.

## What is the density of air at 36000 ft?

Hg (500 mb) or 7.35 pounds per square inch. At 36,000 feet the pressure decreases to half again to about 6.71 in. Hg (225 mb) or about 3.30 pounds per square inch.

Where is air density the highest?

Since air density is the number of air molecules in a given space (volume), air density is typically greatest at the surface or sea level (where it is squeezed by the weight of the entire atmosphere above) and decreases as we move up in the atmosphere because the weight of air above becomes less and hence there is less …

### What is the density of air at 25 C?

1.168 kg/m3
At standard ambient temperature and pressure (25 °C and 100 kPa), dry air has a density of ρSATP = 1.168 kg/m3.

What is the density of air at room temperature?

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). At 20 degrees C and 101.325 kPa, the density of dry air is 1.2041 kg/m3.

#### How much does air density change with altitude?

Air density is higher at lower altitudes. There is more space between air molecules at higher altitudes. There is less oxygen to breathe at the top of a high mountain than there is at sea level.
