Chapter 1, Problem 1.23NP

Interpretation Introduction

Interpretation:The barometric pressure in Santa Fe needs to be calculated in Pa for which the value of z is 7000 ft assuming the mean molar mass of gas 28.9 g/mol and temperature is 25.0°C.

Concept Introduction: The partial pressure of the component of air above the sea level in the atmosphere of the earth can be calculated as follows:

  $P_i=P_i^o{e}^{-M_{i}gz/RT}$

Here, $P_i$ is partial pressure at z height, $P_i^o$ is partial pressure of component i at the sea level, g is acceleration due to gravity, R is Universal gas constant, M is molar mass of the gas and T is temperature.
