Consider the air over a city to be a box 100km on a side that reaches up to an altitude of 1.0 km. The air is blowing into the box along one of its sides with a speed of 4 m/s. Suppose an air pollutant with a reaction rate of K = 0.30/hr is emitted into the box at a total mass loading rate of 10 kg/s. Find the steady state concentration if the air in the box is assumed to be perfectly mixed.
