Influence of vegetable oil in the viscosity of biodiesel-a review
(2008-12-01)
Viscosity is a measure fluid resistance to flowing, affecting the fuel spray in the combustion chamber and, by this way, thus the formation of carbon deposits. The analysis of the influence of vegetable oil viscosity in ...
The application of neural networks to the analysis of dissolved gases in insulating oil used in transformers
(Institute of Electrical and Electronics Engineers (IEEE), 2000-01-01)
The state of insulating oils used in transformers is determined through the accomplishment of physical-chemical tests, which determine the state of the oil, as well as the chromatography test, which determines possible ...
