VARIATION OF SATURATION VAPOR PRESSURE OVER WATER WITH 



TEMPERATURE 



This table contains values of — ^ where e w is the saturation vapor pressure over water and 



dT 

 T is the temperature (°K.). Values were computed from the formula 



dT 





6790.5 - 5.028087 + 4916.8 X 10- 0304J T 2 + 174209 X 10 



obtained by differentiating the Goff-Gratch equation for the saturation vapor pressure over water 

 (see p. 350).
