Testing and Modeling of Petroleum Based Lubricating Oils by an Improvised System
Journal Title: Leonardo Electronic Journal of Practices and Technologies - Year 2005, Vol 4, Issue 7
Abstract
The effect of temperature, pressure and time was tested on the viscosities of ten lubricant samples using 23 factorial designs, also an analysis of variance procedure and subsequently a regression model was carried out for each sample.The result showed that for samples II, V, VI and VIII temperature alone has significant effect on their viscosities while pressure, time and their interactions have no significant effect. For samples I, VII, IX and X, temperature, pressure and time have significant effect and for sample III, all the process variables and their interaction have significant effect except for the interaction between pressure and time. Samples II, V, VI and VIII are of best performance since only temperature affects their viscosities. The coefficient of regression square (R2) is 1.0 for all the samples and this shows a very good correlation between the variables.The regression model suits the experimented values close and could be used for test for the same formulation without laboratory experiment.
