Questions & Answers

QUESTION:

Problem 31P

A gymnasium is 16 m high. By what percent is the air pressure at the floor greater than the air pressure at the ceiling?

ANSWER:

Step 1 of 3

We are going to find the percentage of difference in the air pressure at the ground and the height 16 above the ground in a gymnasium

The density of air \(\rho=1.29 \mathrm{~kg} / \mathrm{m}^{3}\)

The acceleration due to gravity \(\mathrm{g}=9.8 \mathrm{~m} / \mathrm{s}^{2}\)

The height above the ground \(\mathrm{h}=16 \mathrm{~m}\)

The atmospheric pressure \(\mathrm{p}_{0}=101.325 \mathrm{kPa}\)
