Water 12 L/min Mixture 4 L/min 100 L 100 L Mixture 16 L/min Mixture 12 L/min Mixing tank A holds 100 L of water in which 0.04 kg of salts is dissolved. Suppose tank B contains 100 L of water which has 0.02 kg of salt. Liquid is pumped in and out of the tanks as indicated in the figure. The mixture exchanged between the two tanks and the liquid pumped out of tank B is assumed to be well...

Consider two brine tanks connected as shown in the figure. The brine solution is pumped from tank 1 into tank 2 at a rate of 10 L/min10 L/min, and from tank 2 into tank 1 at a rate of 10 L/min10 L/min. Suppose there are 50 L50 L of brine in tank 1 and 25 L25 L of brine in tank 2. Let xx be the amount of salt, in kilograms, in tank 1 after tt minutes have elapsed, and...

I just need help understand where I get the 7 for the dx/dt 1. (5 points) Two large tanks, each holding 100 L of liquid, are interconnected by pipes, with the liquid flowing from Tank A into Tank B at a rate of 3 L/min and from B into A at a rate of 1 L/min. The liquid inside each tank is kept well stirred. A brine solution with a concentration of 0.2 kg/L of salt flows into Tank A...
Consider two brine tanks connected as shown in figure I below. Tank 1 contains xit) pounds of salt in 100 wal of brine and tank 2 contains vit) pounds of salt in 200 gal of brine. The brine in each tank is kept uniform by stirring, and brine is pumped from each tank to the other at the rates indicated in figure 1. In addition, fresh water flows into tank 1 at 20 gal/min, and the brine in tank 2...
(3 points) Consider the two tank apparatus shown in the figure. Each tank has capacity 950950 liters and initially contains 100100 liters of fresh water. At time t=0t=0, the well-stirred mixing process begins. Suppose that the concentration of brine flowing into Tank 1 via the top tube is 11 kilograms per liter, and that the flow rates are r1=r3=4r1=r3=4 liters per minute, and r2=r4=13r2=r4=13 liters per minute. (a) Determine the volume of solution in each tank as a function of...
Please answer the whole question (part a and b) A. Suppose a brine containing 0.6 kg of salt per liter runs into a tank initially filled with 500 L of water containing 3 kg of salt. The brine enters the tank at a rate of 5 L/min. The mixture, kept uniform by stirring, is flowing out at the rate of 5 L/min (see Figure, where a = 5, c 0.6, tc-500, and Ao = 3) 7. a Umin ckg/L A(C)...
Please solve thank you. In Problem 27 of Exercises 4.9 you were asked to solve the following linear system dx1 1 dt 50 dx2 1 2 dt 50 75 dx3 1 2 x2 75 dt 25 using elimination techniques. This system is a mathematical model for the number of pounds of salt x(t), x2(t), and x3(t) in the connected mixing tanks A, B, and C shown in Figure 3.3.8 on page 112 (a) Use the eigenvalue method of this section...
DIFFERENTIAL EQUATIONS WEBWORK PROBLEM If you can't read the picture: Consider two interconnected tanks as shown in the figure above. Tank 1 initial contains 10 L (liters) of water and 215 g of salt, while tank 2 initially contains 90 L of water and 355 g of salt. Water containing 50 g/L of salt is poured into tank1 at a rate of 4 L/min while the mixture flowing into tank 2 contains a salt concentration of 45 g/L of salt...
