| The pilot climbed to an altitude of 2 km. What is the atmospheric pressure of air at this height if at the surface of the earth it is equal to 750 mm Hg?
Answer: the pressure at an altitude of 2 km will be 550 mm Hg.
Solution:
1) In the troposphere, on average, the pressure decreases by 10 mm Hg. for every 100 m of height. Let’s calculate how much the pressure will decrease at an altitude of 2 km (2000 m).
2000 m / 10 mm Hg = 200 mm Hg
2) Knowing the atmospheric pressure at the earth’s surface (750 mm Hg), we will calculate the pressure at an altitude of 2 km.
750 – 200 = 550 (mmHg)
