A simple way to model air pollution over a city is with a box model that assumes complete mixing and limited capability for the pollution to disperse horizontally or vertically except in the direction of the prevailing winds. An example is a town located in a valley with in inversion layer above it that prevents vertical convection. This inversion is at an altitude of 0.75 km. There is a wind entering the town at a speed of 3.00m/s; the town is 20.0km wide perpendicular to the wind and 25.0 km long in the direction of the wind; carbon monoxide is being emitted in the town at a constant rate of 250.0kg/s. Assume the carbon monoxide has a decay rate coefficient of k=0.10/hr.
1. What is the steady-state concentration fo carbon monoxide in the town?
2. Suppose a nearby storm passage causes the wind speed in the town to suddenly increase to 10.0m/s.
3.What is the carbon monoxide concentration one hour later?
