Despre o problemă de concentraţie a soluţiei

Abstract

In the present paper is examined a problem of a technological nature, wich requires to establish the quantity of salt in a solution depending on time. The mathematical model of the problem is deduced according to the form of a differential equation. This equation can be resolved in quadratures. Two important particular cases are examined, which contain initial conditions as well. In this cases the equation can be resolved completely.
