A 100 m^3 tank is full of water The water contains a pollutant z at a concentration of 0.5 g/m^3. Cleaner water, with a pollutant concentration of 0.1 g/m^3 is pumped into a well mixed tank at a rate of 4 m^3 /sec Water flows out of the tank through an overflow valve at the same rate as it is pumped in a) Determine the amount and concentration of the pollutant in the tank as a function of time b) At what time will the concentration be 0.3 g/m^3 c) At what time will the concentration be 0.2 g/m^3

Question
A 100 m^3 tank is full of water The water contains a pollutant z at a concentration of 0.5 g/m^3.
Cleaner water, with a pollutant concentration of 0.1 g/m^3 is pumped into a well mixed tank at a rate of 4 m^3 /sec
Water flows out of the tank through an overflow valve at the same rate as it is pumped in
a) Determine the amount and concentration of the pollutant in the tank as a function of time
b) At what time will the concentration be 0.3 g/m^3
c) At what time will the concentration be 0.2 g/m^3
