Starting with this equation dP/ dy = ρg (1) and this relationship P/ Po = ρ/ ρo (2) where Po and ρo are pressure and density at sea level. Assume g is constant and y = 0 at sea level. (a) Determine the variation in pressure in the earth’s atmosphere as a function of elevation y above the sea level. (b) At what elevation is the air pressure equal to half the pressure at sea level?

The atmospheric pressure varies proportionally from sea level to height, and the air temperature drops by 6K for every T km increase (a) Draw a cylindrical volume that is height inside the atmosphere, and then calculate the pressure change and expression (dP/dy-pg) depending on the height. (b) obtain the temperature change of the atmosphere accordingto the height y(km) in the place where the sea level (y-0) is at ToK temperature. (c) obtain a barometric equation which allows for the change...

Question 2 (20 points) Venus has mass my = 4.87 x 1024 kg and radius Ry = 6.05 x 103 km. Surface conditions are temperature To = 740 K, and pressure Po = 9.3 MPa. The lapse rate is approximately constant for most of the troposphere, up to 2 60 km where T1 263 K. Its atmosphere can be approximated as 100% carbon dioxide, CO2. You can assume that gravity is constant at its sea-level value. Using your result from...
