A solar collector in which the absorber is contained in a sealed glass tube, thereby providing for relatively high temperature heat gain.

The escape of water molecules from a liquid to the gas phase at the surface of a body of water.2. The conversion of a liquid to a vapor (gas), usually by means of heat.

Same as atmometer.

See hook gauge.

The ratio of the actual amount of water evaporated into the atmosphere to the evaporative power. Also called relative evaporation.

A type of atmometer. It is a pan used in the measurement of the evaporation of water into the atmosphere. The NWS Class A pan is a cylindrical container 48 inches in diameter and 10 inches deep.

The volume of liquid water evaporated per unit area in unit time. usually measured as the depth of liquid water lost per unit time from the whole area.

The physical process by which a liquid or solid is transformed into the gaseous state. For this process a mechanical device uses the outside air's heat to evaporate water that is held by pads inside the cooler. The heat is drawn out of the air through thi ...

A measure of the degree to which the weather or climate of a region is favorable to the process of evaporation. Usually considered to be the rate of evaporation. under existing atmospheric conditions, from a surface of water which is chemically pure and h ...

The chamber located on suction side of cap tube, in which freon is evaporated to cause cooling in a refrigeration system.

The inner coil in a heat pump that, during the cooling mode, absorbs heat from the inside air and boils the liquid refrigerant to a vapor, which cools the house.

Same as atmometer.

Instrument which measures and records the amount of evaporation over time.

The combined processes by which water is transferred from the earth's surface to the atmosphere: evaporation of liquid or solid water plus transpiration from plants.

An instrument which measures the rate of evapotranspiration. It consists of a vegetation soil tank so designed that all water added to the tank and all water left after evapotranspiration can be measured.

When the draft of a ship fore and aft are the same. Floating level (no list).

When used in pricing terms such as "Ex Factory" or "Ex Dock," it signifies that the price quoted applies only at the point of origin indicated.
