A room contains fresh air initially. At the beginning, the mixture of smoke of cigarette and air is introduced into the room at a rate of 0.02 m3/min that involve 0.1 m3 CO/m3 air. The room is well circulated and mixture is allowed to leave the room at a rate of 0.02 m3/min. Assume that the densities of gases are equal and Vroom=50 m3. Derive a mathematical model and use Laplace Transformation method to find the concentration of CO at any time. Calculate the concentration of CO in the room after 2 h.
