Lab 3-4: Combine all the steps and solve a problem

For this lab, combine what you learned in labs 3-1 to 3-3 to solve an air quality problem

You have finished designing a treatment system for removing arsenic from landfll leachate. The treatment system you developed involves the complete reduction of Arsenic (As) species to Arsine gas (\(H_3As\)). Arsine gas is a known human carcinogen and you need to determine if the Arsine concentration leaving the treatment facility requires further treatment to ensure safe concentrations at the site boundary, a distance x = 2 km downwind. The treatment plant has a predicted emission rate of 300 mg/s The smokestack has an effective height, z = 100 m. The average wind speed measured at a height of 10 m is 6 m/s (\(U_{10}\) = 6 m/s). Assume a fall afternoon and rural topography.

1. Find the ground level oncentration leaving the site boundary.

#You can use this cell to enter the code to solve part 1

2. Calculate and plot the centerline ground level concentration versus distance from the stack, C(x).

# More code here

3. Find the magnitude and location of the peak ground level concentration.

# and make a nice plot here
