This is one of the most common problems for differential equation course. Homework Statement A tank containing 400 liters of water has 10 kg of salt solute (dissolved salt). 5 years ago | 9 views. Mixing Problem (Single Tank) Mixing Problem(Two Tank) Mixing Problem (Three Tank) Example : Mixing Problem . University Math Help. The problem is to determine the quantity of salt in the tank as a function of time. Playing next. (See Example 6 in that section.) Part 1: Mixing Problems with Differential Equations. The solution inside the tank is kept well stirred and flows out of the tank at a rate of 3 L/min. Here are a set of practice problems for the Differential Equations notes. This is an example of a mixing problem. This is a question from my differential equations class. They’re word problems that require us to create a separable differential equation based on the concentration of a substance in a tank. To construct a tractable mathematical model for mixing problems we assume in our examples (and most exercises) that the mixture is stirred instantly so that the salt is always uniformly distributed throughout the mixture. Hence 300lb of salt, approximately. Jennell Tompkins. A typical mixing problem deals with the amount of salt in a mixing tank.
