Question

Duel Mixing Tanks. A brine solution with a fixed salt concentration of 20 g/L is pumped into a tank at the constant rate of 1 L/s. The tank initially contains 100 L of salt-free water, and the well-mixed solution drains at the rate of 1 L/s into a second tank which initially contains 50 L of salt-free water. The second tank also drains at a rate of 1 L/s. Find
A_1 (t)= the amount of salt in the first tank at time t
A_2 (t)= the amount of salt in the second tank at time t

Answer 1

I'm a little rusty on these tank problems :)
I think I can help, just need a few minutes to brush up on the material.

Answer 2

so we initially have 100 L of water in a tank, and we are adding 20g salt per second, but its draining into another tank which contains 50 L of water, and this other tank also drains at 1 L per second.

Answer 3

sounds like a diffy Q problem

Answer 4

Let's see if we can set up an accurate diagram.
