Abstract

This paper work contains the study of non-stationary dissolution of individual urea granules used as fertilizers. The present study is based on The Generalized Dimensional Analysis and includes comments about the fundamental factors, the important factors, the secondary factors and about the unimportant factors which can control the phenomenon. It also contains experimental determinations on simple and filmed urea granules that lead to a general equation for the dissolving process.
