The Earth's atmosphere normally contains a large number of very small particles, for instance water droplets and carbon soot, generally called aerosols. Consider a spherical water droplet in still air falling under gravity. If the radius of the droplet is 5 microns, what is its maximum speed of fall (the terminal velocity)? The density of water is pw = 1000 kg/m³ and the dynamic viscosity of air at 20°C is 1.8 x 10 kg/m s.

Evangelista Torricelli was the first person to realize that we live at the bottomof an ocean of air. He correctly surmised that the pressure of our atmosphereis attributable to the weight of the air. The density of air at 0°C at the Earth'ssurface is 1.29 kg/m3 . The density decreases with increasing altitude (as theatmosphere thins). On the other hand, if we assume that the density isconstant at 1.29 kg/m3 up to some altitude h, and zero above that altitude, then h would represent the depth of the ocean of air.Use this model to determine the value of h that gives a pressure of 1.00 atmat the surface of the Earth.
