The pressure on Earth's atmosphere as a function of height y above sea level can be determined by assuming g to be constant and that the density of air is proportional to the pressure, i.e., px P.

[Hint: Po = 1.013 x 105 N/m², po = 1.29 kg x m-³] (1) Start by finding a relation between the pressure Po and the density of air po at 0° at sea level (y=0) and the pressure P and density p at height y. Using this relation find an expression for p as a function of P, i.e., p = p(P). (2) Find the pressure as a function y.

Question
The pressure on Earth's atmosphere as a function of height y above sea level can be determined by
assuming g to be constant and that the density of air is proportional to the pressure, i.e., px P.
Note that this assumption is not very accurate since temperature and other weather effects can
influence pressure. [Hint: Po = 1.013 × 105 N/m², po = 1.29 kg x m-³]
(1) Start by finding a relation between the pressure Po and the density of air po at 0° at sea level
(y=0) and the pressure P and density p at height y. Using this relation find an expression
for p as a function of P, i.e., p = p(P).
(2) Find the pressure as a function y.
(3) At what altitude above sea level is the atmospheric pressure equal to half the pressure at sea
level?
