Answer #1

Pressure difference =

Where, H is height difference

   Is density and g is acceleration of gravity ie equal to 9.8 m/s2

1. Pressure difference = 10000m*1.3kg/m3*9.8m/s2

= 127400 pascal. ( 1 kg/(m*s2) = 1 pascal)

2. Pressure difference = 100m*1000kg/m3*9.8m/s2

= 980000 pascal

    1. For an atmosphere in hydrostatic equilibrium the variation of particle number density (# of particles per unit volume) of each species as a function of altitude (z) is found by equating gravitational and pressure forces. The resulting expression is: N(z) = No * e^(-(z - zo)/H) where N0 is a constant for each species, and z0 is an arbitrary reference altitude. The parameter H is called the scale height, which is equal to KT/mg. In the scale height expression...
