Figure 7.15 shows the frequency distribution of various values for the product of H times u for Peoria, Illinois. If the average daily emission rate for carbon monoxide for this city is 2-10' g/(h - mi?) and the standard to be met is 10 mg/m³, what fraction of the time must we implement intermittent control to meet this standard? Assume that the simple box model (Sec. 6.2) applies, that the size of the city is 5 mi by 5 mi, and that the background concentration is 2 mg/m³.

Question

What fraction of the time must we implement ''intermittent control'' to meet this standart? Please use ''simple box model''.

Figure 7.15 shows the frequency distribution of various values for the product of H times u
for Peoria, Illinois. If the average daily emission rate for carbon monoxide for this city
is 2.107 g/(h · mi?) and the standard to be met is 10 mg/m3, what fraction of the time
must we implement intermittent control to meet this standard? Assume that the simple box
model (Sec. 6.2) applies, that the size of the city is 5 mi by 5 mi, and that the background
concentration is 2 mg/m³.
