Consider the air over a city to be a box 100 km on two sides that reaches up to an altitude of 1.0km. clean air is blowing into the box along one of its sides with a speed of 4 m/s. suppose an air pollutant with a degradation reaction rate k = 0.2 hr-1 is emitted into the box at a total rate of 10.0 kg/s.
if the windspeed in this above problem suddenly drops to 1 m/s, estimate the concentration of the pollutant two hours later.

![C(t)=[C_0-C_{2hr}]exp[-(K+Q/V)t]+C_{2hr}\\\\C(2hr)=[10.46-15.25]exp[-(\frac{0.2}{hr}+\frac{1\times 10^8(m^3/s)\times 3600(s/hr)}{1000\times 10^{10}(m^3)})2hr]+15.25\\\\\\[10.446-15.25]\times 0.624 +15.25\\\\12.26\mu g/m^3](/tpl/images/0464/9942/a2710.png)
