Sea Level Pressure Exercise
If you recorded 29.42 in Hg as the atmospheric pressure at an elevation 80 feet above sea level, what is the sea level pressure? Use the Additive Reduction Constant table to derive the answer. Choose the best answer.
The correct answer is a).
At 80 feet, the additive reduction constant is 0.085. Adding this to 29.42 in Hg gives a sea level pressure of 29.51 in Hg.
