Influencia del voltaje sobre las características reológicas del sabajónInfluencia del Voltaje Sobre las Características Reológicas del Sabajón
(Universidad Nacional Abierta y a Distancia, UNAD, 2007-05-15)
With the objective to study the effect of the difference of potential in the rheological parameters, the study of the rheology behaviour of a liquor “sabajón” was made, submissive a difference of potential between 11 volts and 45 volts in 11 applications with a rank of time between 120 second and 630 seconds. In order to determine the meaning of the results and of finding mathematical the models suitable that they give ...
