PPT-Evaporation What is evaporation?

How is evaporation measured How is evaporation estimated Reading Applied Hydrology Sections 35 and 36 With assistance from Dan Siegel and Marcy Litvak Evaporation What is evaporation How is evaporation measured. To relate the boiling point of water to its vapor pressure . Objectives. A. . Evaporation and Vapor Pressure . Vaporization or evaporation . Endothermic . A. . Evaporation and Vapor Pressure . Amount of liquid first decreases then becomes constant . Evaporation is the process in which a liquid changes to the gaseous state at the free surface, below the boiling point through the transfer of heat energy . The rate of evaporation is depended on the By J. With EVAPORATION By TOR STUDIES GEOLOGICAL An the // W^estern UNITED Implementing a Soil Water . Oxygen . Isotope Model in . Matlab. Erik . Oerter.

Daily estimates are used for operations and accounting at certain reservoirs, but not all. Estimates are typically based on pan evaporation measurements or reference evapotranspiration.
