A tank initially contains 120 L of pure water. A salt mixture containing a concentration of 1.5 g/L enters the tank at a rate of 2 L/min, and the well-stirred mixture leaves the tank at the same rate. Find an expression for the amount of salt in the tank at any time t. Also, find the limiting amount of salt in the tank as t +0. (10 points)
4. A tank initially contains 100 liters (L) of water with a salt concentration of 20 g/L. A mixture with a salt concentration of 5 g/L flows into the tank at a rate of 5 Umin while the well-mixed fuid in the tank flows out at the rate of 3 L/min. Determine the concentration of salt (g/L) in the tank when the volume in the tank reaches 400 liters.

1. A tank is used for chemical experiments. It initially contains 10001 of a solution with concentration 5g/l. Pure water is used to reduce the concentration of the chemical solution. It enters the tank at a rate of 21/min and the well-stirred mixture leaves the tank at the same rate. Let Q(t) denote the mass of the chemical in the tank (measured in g) at time t in minutes. (a) Write an IVP that models the above described process. (8...
