Question
![A brine solution of salt flows at a constant rate of 4 L/min into a large tank that initially held 100 L of pure water. The solution inside the tank is kept well
stirred and flows out of the tank at a rate of 3 L/min.
4 L/min
0.2 kg. of salt /L
x (t)
At t=0
100 L
Pure water
x(t) kg. of salt
If the concentration of salt in the brine entering the tank is 0.2 kg/L, determine the mass of salt in the tank after t min.
=
(100+t)/5-20(100)^5(100+t)^-5
3 L/min
kg.
When will the concentration of salt in the tank reach 0.1 kg/L?
