Calculate Air Density Ratio



Formula

To calculate the Air Density Ratio:

\[ R = \frac{\rho_a}{\rho_s} \]

Where:

What is Air Density Ratio?

The air density ratio is a measure of how the density of air changes with altitude compared to its density at sea level. This ratio is important in various fields such as aviation, meteorology, and environmental science, as it affects the performance of aircraft, weather patterns, and the dispersion of pollutants. Understanding the air density ratio helps in evaluating how air pressure and temperature variations with altitude influence the density of air.

Example Calculation

Let's assume the following values:

Using the formula:

\[ R = \frac{1.0}{1.225} \approx 0.82 \]

The Air Density Ratio is approximately 0.82.
