The air in a room 10 ft by 8 ft by 8 ft is 4% carbon monoxide. Starting at t= 0, fresh air containing no carbon monoxide is blown into the room at a rate of 75 ft/min. If air in the room flows out through a vent at the same rate, when will the air in the room be 0.01% carbon monoxide? minutes. The air in the room will be 0.01% carbon monoxide after (Round to two decimal places...

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.

56. Fresh air is introduced into a room at such a rate that the air in the room is changed every 5 minutes. The room is 30 by 30 by 10 ft and the air in the room is at 70 °F with a percentage humidity of 60. Outside air at a temperature of 60 °F is used as air supply. The outside air is heated to the room temperature by a heat exchanger. How many BtU per hour must...

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...
