A chemical flows into a storage tank at a rate of `(180 + 3t)` liters per minute, where t is the time in minutes and `0 <= t <= 60.` Find the amount of the chemical that flows into the tank during the first 20 minutes.

A tank initially contains 50 litres of pure water. Starting at time t = 0 a brine containing with 2 grams of dissolved salt per litre flows into the tank at the rate of 3 litres per minutes. The mixture is kept uniform by stirring and the well - stirred mixture simultaneously flows out of the tank at the same rate. Find the amount of salt present in the tank at any time t gt 0 .

A tank contains 5000 litres of pure water. Brine (very salty water) that contains 30 of salt per litre of water is pumped into grams the tank at a rate of 25 litres per minute. The concentration of salt water after t minutes (in grams per litre) is C(t)=(30t)/(200+t) .What happens to the concentration as trarrinfty ?
