Problem 20E

With the assumption that the air temperature is a uniform 0.0°C (as in Example 18.4), what is the density of the air at an altitude of 1.00 km as a percentage of the density at the surface?

Step-by-Step Solution:
Step 1 of 3

Solution 20E We need to first find the expression for density with height. This can be derived from the expression of pressure as shown below. pM We have density = RT …..(1) RTy The variation of pressure with height is given by p = p e 0 …..(2) Here, p =0tmospheric pressure , M =molar mass of air, g =acceleration due to gravity y =height, R =universal gas constant, T =absolute temperature 0 Given, temperature T = 0 C = 273.15 K Altitude y = 1.00 km = 1000 m M = 0.029 kg/mol R = 8.314 J/mol.K g = 9.8 m/s...
