  2. Pan evaporation - Wikipedia

    en.wikipedia.org/wiki/Pan_evaporation

    An evaporation pan is used to hold water during observations for the determination of the quantity of evaporation at a given location. Such pans are of varying sizes and shapes, the most commonly used being circular or square. [3] The best known of the pans are the "Class A" evaporation pan and the "Sunken Colorado Pan". [4]

  3. Vacuum evaporation - Wikipedia

    en.wikipedia.org/wiki/Vacuum_evaporation

    Vacuum evaporation plant vacuum pans in a beet sugar factory. In the sugar industry vacuum evaporation is used in the crystallization of sucrose solutions. Traditionally this process was performed in batch mode, but nowadays continuous vacuum pans are available. [3]

  4. Evaporation - Wikipedia

    en.wikipedia.org/wiki/Evaporation

    Evaporation is an essential part of the water cycle. The sun (solar energy) drives evaporation of water from oceans, lakes, moisture in the soil, and other sources of water. In hydrology, evaporation and transpiration (which involves evaporation within plant stomata) are collectively termed evapotranspiration. Evaporation of water occurs when ...

  9. Potential evapotranspiration - Wikipedia

    en.wikipedia.org/wiki/Potential_evapotranspiration

    Monthly estimated potential evapotranspiration and measured pan evaporation for two locations in Hawaii, Hilo and Pahala. Potential evapotranspiration is usually measured indirectly, from other climatic factors, but also depends on the surface type, such as free water (for lakes and oceans), the soil type for bare soil, and also the density and diversity of vegetation.
