Abstract
The following physical parameters have been computed for the atmospher e of Venus between 65 and 90 km, by intervals of 1 km. (1) Pressure, ( 2) Density, (3) Speed of sound, (4) Number density, (5) Density scale, (6) Pressure scale, (7) Collisional frequency, (8) Mean particle velo city (9) Mean free path, (10) Columnar mass, (11) Viscosity. For these calculations we have used the temperature altitude measurements of Ve nera 15 and 16 at 52 degrees N and 72 degrees N latitudes, the night a nd 70 degrees N and 72 degrees N latitudes the day.
