WebThis means that the atmospheric pressure at the surface of the Earth stays relatively constant. The value of the atmospheric pressure at the surface of the Earth is stuck right around 1.01 \times10^5 Pa 1.01×105P a. WebExample: A car tire gauge measures a tire pressure of 32.0 psi. The local atmospheric pressure is 14.2 psi. What is the absolute pressure of the air in the tire? Solution: The tire gauge measures gage pressure, relative to the local value of atmospheric pressure. Thus, p = p g + p a = 32.0 + 14.2 psi = 46.2 psia. Note that in the English system ...
