PPT-Evaporation and Transpiration

Evapotranspiration or ET 62 of precipitation that falls on the continents is evaporated Understanding and predicting climate change QPET PET is the water available for use ET loss supports ecosystems and agriculture.

Look at these wet clothes, how are they going to dry?. Even in winter?. . Glossary . Transpiration – the loss of water vapour from the leaves of plants through the stomata when they are open to allow gas exchange for photosynthesis.. Condensation?. Precipitation?.

Organisms such as plants and animals thrive in certain habitats.. Daily Operations and Accounting. 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. Liquids have molecules moving around in them. . Temperature is the average kinetic energy (which depends on the speed) of these molecules.. Some are moving. faster than others!. If they are moving fast enough, at just the right angle,. How is evaporation measured?. How is evaporation estimated?. Reading: Applied Hydrology Sections 3.5 and 3.6. With assistance from Dan Siegel and Marcy Litvak. Evaporation. What is evaporation?. How is evaporation measured?. A process whereby liquid water is . converted to water vapour. and . removed from the vapour surface.. Evaporation consists of 2 components i.e. The energy component and the aerodynamic component. The energy component is responsible conversion of liquid water to water vapour. Alison Radei.
