Revision History for SIR 2013-5188 Timothy H. Diehl, Melissa A. Harris, Jennifer C. Murphy, Susan S. Hutson, and David E. Ladd Methods for Estimating Water Consumption for Thermoelectric Power Plants in the United States ----------------------------------------------------- Posted online November 22, 2013 ----------------------------------------------------- Revised and reposted November 06, 2014, version 1.1 The Appendix 4 spreadsheet was revised; these revisions had no effect on the body of the report. Three tabs("Ward equation 1 2 3 14", "Ward Constants", and "Ward Eqn 12") were added to provide background information to the main reference on which the spreadsheet is based, which is an article that will not be availble to most readers. Three other tabs ("altitude vs. air pressure", "Lowe 1977 e(T)", and "unsaturated vapor pressure") were added to provide background on important psychrometric equations used in the model. Minor editorial changes were made in the "Forced Evaporation" and "Read Me" tabs to improve readability. The method of calculation, and hence the output from any given input, did not change.
