35Atmospheric icing — occurs when water droplets in the air freeze on objects they contact. This is very dangerous on aircraft, as the built up ice changes the aerodynamics of the flight surfaces, and can cause loss of lift, with an increased risk of a subsequent… …
36Graupel — (also called snow pellets) refers to precipitation that forms when supercooled droplets of water condense on a snowflake, forming a 2 ndash;5 mm ball of rime; the snowflake acts as a nucleus of condensation in this process. The term is derived… …
37Slurry ice — is a phase changing refrigerant comprised of millions of ice “micro crystals” (typically 0.1 to 1 mm in diameter) formed and suspended within a solution of water and a freezing point depressant. Some compounds used in the field are salt (sodium… …
38ice in lakes and rivers — Introduction a sheet or stretch of ice forming on the surface of lakes and rivers when the temperature drops below freezing (0° C [32° F]). The nature of the ice formations may be as simple as a floating layer that gradually thickens, or it …
39industrial glass — Introduction solid material that is normally lustrous and transparent in appearance and that shows great durability under exposure to the natural elements. These three properties lustre, transparency, and durability make glass a favoured… …
