Laramie wyoming has an altitude of 7,165 feet.
what is the mean atmospheric pressure, p, there assuming an isothermal atmosphere at 0 °c? assume air is 20% o₂and 80% n₂. given that the pressure
of an ideal gas, p, with po = pressure at sea level in bars, varies with height, h, and the gravitational constant, g = 9.8 m/s²:
p = pₒ exp(-gmh / rt)
