Over a 20-minute sampling time, 40.0 grams of water are collected. Calculate the NO2 concentration in the stack.
After calculation there is 737 ppm Of NO2 in the stack. How Do proceed through the next part of the problem??
Assuming that the average stack gas velocity is 10.0 m/s and stack is circular with a 3.0 meter diameter, calculate the mass emissions rate of NO2 in kg/day.
