A large mixing tank initially holds 1000 L of brine. Another brine solution is pumped into the tank at a rate of 10 . When the solution is well stirred, min it is then pumped out at a slower rate of 7.5 . If the concentration of min salt in the brine entering the tank is 0. 25 kg, derive the differential L equation of the salt concentration S(t) in the tank at any time t.
