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`?

The concentration of liquid (in grams/litre)is given by C(t)=(25t)/(205+5t) .what happens to the concentrations at trarr infty .

A tank contains 1000 litres of water and it flows out at the rate of 5 litres per second. How much water is there in the tank after each second? Write their numbers as a sequence.

Water running in a cylindrical pipe of inner diameter 7cm, is collected in a container at the rate of 192.5 litres per minute.Find the rate flow of water in the pipe in km/hr .

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 .
