If at the foot of the mountain the pressure is 745 mm Hg. Art., what is the pressure at an altitude of 337 meters?

Before solving this problem, the following rule should be remembered: with an increase in altitude for every 10 meters, atmospheric pressure will drop by 1 mm Hg. Thus, we can find out how the atmospheric pressure will change. To do this, just do the following:

337 ÷ 10 = 33.7 mm Hg

With this data, we can now calculate the pressure at the top of the mountain. Means,

745 – 33.7 = 711.3 mm Hg

Thus, at the top of the mountain, atmospheric pressure will be 711.3 mm Hg.
