The Centralia power plant emits SO2 at the rate of 150 g/s. It has an effective stack height of 50 m. Surface winds at 10 m are steady at 2.5 m/s and it is a fall afternoon.
a) Calculate the ground level SO2 concentration in ug / m3 at a point 4 km downwind and 0.1 km in the cross wind direction.
b) What is the maximum downwind concentration and at what distance does this occur?
c) There is a town with an SO2 monitor 20 km downwind of the power plant. How large can Q in g/s be if SO2 concentrations are to be kept below 365 ug/m3 for the conditions listed
