Chapter 3, Problem 127P(choose chapter or problem)
Problem 127P
The average atmospheric pressure on earth is approximated as a function of altitude by the relation Patm= 101.325 (1 – 0.02256z)5.256, where Patm is the atmospheric pressure in kPa and z is the altitude in km with z = 0 at sea level. Determine the approximate atmospheric pressures at Atlanta (z = 306 m), Denver(z= 1610 m), Mexico City (z = 2309 m), and the top of Mount Everest (z = 8848 m).

Problem 127P
The average atmospheric pressure on earth is approximated as a function of altitude by the relation Patm= 101.325 (1 – 0.02256z)5.256, where Patm is the atmospheric pressure in kPa and z is the altitude in km with z = 0 at sea level. Determine the approximate atmospheric pressures at Atlanta (z = 306 m), Denver(z= 1610 m), Mexico City (z = 2309 m), and the top of Mount Everest (z = 8848 m).
ANSWER:
Step 1
Pressure is not constant in different altitude, pressure varies with altitude.Now we can find atmospheric pressure at particular height.
Where z is the height of the locations
Now we have to find atmospheric pressure at different places and the height of the locations are given.
