| Abstract |
This report provides a summary of the calculations used to determine relative and specific humidity of moisture in air for mobile source (motor vehicle and engine) emission and fuel economy testing at the U.S. Environmental Protection Agency Motor Vehicle Emissions Laboratory in Ann Arbor, Michigan. The reference includes calculations required to determine the saturation vapor pressure of water, psychrometric equations used to calculate the partial pressure of water vapor for wet-bulb psychrometers, and equations for the enhancement factor of water and ice. Also included are the methods used from 1971 to the present (1982). |
