A specific gravity scale developed by the American Petroleum Institute (API) for measuring the relative density of various petroleum liquids, expressed in degrees. API gravity is gradated in degrees on a hydrometer instrument and was designed so that most values would fall between 10Â° and 70Â° API gravity. The arbitrary formula used to obtain this effect is: API gravity = (141.5/SG at 60Â°F) - 131.5, where SG is the specific gravity of the fluid.
[ 2 syll. co-lom-be, col-o- mbe ] The baby girl name Colombe is pronounced KowL AH M- â . Colombe is of Latin origin and it is used mainly in the French language. It is derived from the element columba meaning 'dove'. Columba (Latin) is an old form of Colombe. The name Columba was borne by both men and women.
In the modern idiom the name has at least four spelling variations including Coldbeck, Colebeck, Coulbeck etc. and they are composed of the Olde Norse elements kaldr meaning cold and bekkr a stream. The Olde English elements col meaning cool and burna a stream, give rise to a similar group of names ie.Colbourne, Colborn etc. The first recorded spelling of the family name is shown to be that of Geoffrey de Colebrunn. which was dated 1208, in the Yorkshire Place Name Register.during the reign of King John, known as Lackland, 1199 - 1216.he first recorded spelling of the family name is shown to be that of Geoffrey de Colebrunn. which was dated 1208, in the Yorkshire Place Name Register. during the reign of King John, known as Lackland, 1199 - 1216.
