10. Suppose that a room containing 1200 fts of air is initially free of carbon monoxide (CO). Beginning at time t = 0 cigarette smoke containing 4% carbon monoxide is introduced to the room at a rate of 0.1 ff per minute. The well-circulated mixture is allowed to leave the room at the same rate. Let Aſt) represent the amount of CO in the room in ft after t minutes and 3(t) represents the concentration of CO at time t....

Suppose that a room containing 1900 cubic feet of air is originally free of carbon monoxide (CO). Beginning at time t 0, cigarette smoke containing 3% CO is introduced into the room at a rate of 0.3 cubic feet per minute. The well- circulated smoke and air mixture is allowed to leave the room at the same rate. Let A(t) represent the amount of CO in the room (in cubic feet) after t minutes. (A) Write the DE model for...

A brine solution of salt flows at a constant rate of 8 L/min into a large tank that initially held 100 L of brine solution in which was dissolved 0.1 kg of salt. The solution inside the tank is kept well stirred and flows out of the tank at the same rate. If the concentration of salt in the brine entering the tank is 0.02 kg/L, determine the mass of salt in the tank after t min. When will the...
