SUMMARY

The discussion focuses on calculating gas density at altitude for use in the terminal velocity equation. A specific formula is provided: p = 100 * ((44331 * 514 - z) / (11880 * 516)), where p represents density and z is altitude in meters. This equation simplifies the calculation without the need for complex factors such as dew point, making it accessible for practical applications. The formula is particularly relevant for those interested in aerodynamics and related fields.

PREREQUISITES
  • Understanding of basic physics principles related to gas behavior
  • Familiarity with the concept of terminal velocity
  • Knowledge of altitude measurement in meters
  • Basic algebra for manipulating equations
NEXT STEPS
  • Research the ideal gas law and its applications in density calculations
  • Explore the effects of altitude on atmospheric pressure and density
  • Learn about terminal velocity equations in different mediums
  • Investigate meteorological factors affecting gas density beyond altitude
USEFUL FOR

Aerodynamics enthusiasts, physics students, engineers, and anyone involved in calculating terminal velocity in varying atmospheric conditions.

Hi I have been reading a lot about how to calculate gas density and I am stumped. What I would like to know is how to calculate the gas density as apposed to altitude so I can use it in the terminal velocity equation found here http://www.grc.nasa.gov/WWW/k-12/airplane/termv.html
I would like to know if there is a simple equation that can calculate the gas density with only a few factors and not with dew point and other factors that I have seen in Meteorology.
Thanks for any help with this

Hi I found an formula for calculating gas density at height it anyone needs it
p = 100 * ((44331 * 514 - z)/ (11880 * 516))
p is density and z is altitued in meters.
