What is the standard pressure of air at mean sea level?

A. About 10.1 psi
B. About 12.3 psi
C. About 14.7 psi
D. About 16.5 psi
E. About 18.2 psi

Answer :

The standard pressure of air at mean sea level is a commonly known value in atmospheric science. This pressure is often measured in psi, which stands for pounds per square inch.

One of the standard values used for atmospheric pressure at sea level is approximately 14.7 psi. This value represents the average pressure exerted by the Earth's atmosphere at sea level.

Therefore, the correct answer to the question about the standard pressure of air at mean sea level is:

About 14.7 psi.
