The measured speed of sound at that altitude is 295.4 m/s.

Mean Gradient. However, typical flight routes do not travel above Mount Everest as the mountains create unforgiving weather. ,Ve are now in possession of many good measurements made in various countries. Design & Manufacturability Air is almost an ideal gas. A "Standard Atmosphere" can be regarded as an average pressure, temperature and air density for various altitudes. They cannot be entirely due to errors in measurement. 73 The hottest recorded temperature on Earth was an experiment conducted at the Large Hadron Collider at CERN. 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/m). English speaking countries previously used the Fahrenheit temperature scale for medical, industrial, and climatic purposes until 1960, when it was replaced by Celsius scale. He has extensive experience with a wide variety of cameras, the latest editing software, and stays current with all the newest trends in editing and cinematography. Carriers avoid a massive amount of turbulence that would occur at lower levels. The calculator below can be used to calculate air dynamic or kinematic viscosity at given temperatures and atmospheric pressure. Subtracting this from 35000 feet gives 35000 - 34320 = 680 feet. How cold is it at 8000 feet?
