Stack monitoring data is available for a paint booth. The measured average concentration of

toluene is 0.1 ppmv (dry gas basis). The moisture content in the stack is typically 10%, and

stack conditions are maintained at 80 °C and atmospheric pressure. The stack gas velocity is 8

m/s. The diameter of the stack is 0.3 m. If the paint booth is used 8 hours per day, 5 days per

week, 52 weeks per year then calculate the:

a) Volumetric flowrate. (m³/s)

b) Molar volume (L/mol)

c) Air release (lbs/year)

NOTE: Air Release = (volumetric flow, m³ /s) × (concentration, mg/m³) × (operating time,

sec/year)
