CONT

The Bellani plate [used to measure evaporation] consists of a thin, porous, black ceramic disk, 7.5 cm in diameter, fused to the large end of a glazed, ceramic funnel. Water is conducted through the lower open end of the funnel from a burette which acts as a reservoir and a measuring device.

CONT

Use of Bellani plate evaporimeters for estimation of PET [potential evapotranspiration].

OBS

Evaporimeter(atmometer) An evaporimeter consists of a flat, porous ceramic disk(Bellani plate) in which water is drawn up by capillary action as water is evaporated from the disk. It is used to directly estimate crop evapotranspiration rate. Several commercial models can be easily installed near the edge of a field or on a roadway in a field.(The unit must be located far enough into the field to avoid field boundary effects.) One commercial model provides a green canvas-like material covering the ceramic disc to simulate crop leaf color. Reasonably good correlation has been found between field measurements and that calculated from Penman-type equations. Small difference in evaporation rates may be found between individual meters. Maintaining water levels and removal for freeze protection are necessary.

Appareil de mesure de l'eau évaporée, dont le capteur est un disque de porcelaine noircie, d'environ 7,5 centimètres de diamètre et quelques millimètres d'épaisseur, placé horizontalement au sommet d'une cheminée en verre alimentée en eau, sous pression, par un réservoir gradué qui permet la mesure de l'évaporation.

CONT

Il est très difficile de mesurer l'évaporation dans la nature, ou plus exactement l'évapotranspiration, puisqu'il faut tenir compte de la transpiration des plantes. [...] Suivant les pays et les besoins, la mesure est faite avec des dispositifs différents. Citons le bac à évaporation du bureau météorologique des États-Unis [...] le lysimètre, [...] l'évaporomètre Piche, employé en France surtout, [...]; enfin l'atmomètre de Bellani, utilisé dans les stations agricoles du Canada, petite assiette poreuse noire, maintenue humide et placée à quatre pieds au-dessus du sol.

CONT

La plaque de Bellani [utilisée pour mesurer l'évaporation] consiste en un disque de céramique [...] qui est joint à la grande ouverture d'un entonnoir de céramique vitrifié. L'eau est amenée à l'ouverture inférieur de l'entonnoir au moyen d'une burette qui sert en même temps de réservoir et d'appareil de mesure.

CONT

Dowtherm and Dowfrost antifreeze is specially designed for process chiller systems. All chilled water systems can benefit from any of Dow’s specially inhibited ethylene glycol and propylene glycol based solutions. ... Dowtherm SR-1 inhibited ethylene glycol-based fluid. With an operating temperature range of -60°F to 250°F, this is the most widely used fluid for heating and HVAC applications. The specially formulated corrosion inhibitor package is easily maintained, long-lasting and replenishable.

CONT

coolant: Sometimes called anti-freeze, this is a solution of inhibited ethylene glycol or inhibited propylene glycol plus water that circulates through the system to keep the engine cool. It’s also a rust and corrosion inhibitor. Ethylene glycol or propylene glycol is only the anti-freeze part. The corrosion inhibitor is a chemical additive typically TT (tolytriazole) or nitrites as sodium nitrite.

CONT

Antifreeze, Inhibited Ethylene Glycol. Ethylene glycol is used for freeze protection of the coolant. IEG, commonly referred to as "antifreeze, "also contains chemicals that provide a limited pretection against corrosion. The use of an IEG product with a low silicate formulation that meets ASTM D 3306 or GM 6043M requirements is recommended.

OBS

inhibitor: Substance, naturally occurring or a synthetic additive, whose presence in small amounts in a petroleum product retards or prevents the occurrence of certain phenomena considered undesirable, e.g. gum formation in stored gasolines, corrosion in steam turbines. [Definition standardized by ISO.]

OBS

IEG: This might be an in-house or a non-recognized abbreviation; not to be used alone, to avoid any risk of confusion.

OBS

Détartrant désincrustant pour lave-vaisselle industriel. Applications. Produit destiné au détartrage et à la désincrustation des lave-vaisselle industriels, matériels divers, assiettes, plateaux, verres, etc,... Description. Aspect : liquide limpide rose. Nature : acide fort additionné d'un inhibiteur de corrosion.

OBS

La galvanisation à chaud. [...] avant l'immersion dans le bain de zinc, les pièces à galvaniser passent [par le] décapage, [qui] se fait à l'aide d'acide chlorhydrique additionné d'un inhibiteur (3 à 6 mol/l) et permet d'éliminer la calamine et certains autres oxydes présents en surface.

OBS

Le Décalaminox 4A est un décapant acide inhibé spécialement conçu pour éliminer les différents oxydes, sans attaque du métal ainsi que les sables vitrifiés résiduels de fonderie.

OBS

inhibited oils : huiles contenant des inhibiteurs.
