A factory operates heavy machinery which emits pollutant air with a PM2.5 of 700 ug/m3 . The factory has inflow and outflow air vents and an air filter to assist with reducing the PM2.5 concentration of the outflowing air from the factory. The air purifier removes PM2.5 at a rate of 4 m3/hr and has a 80% PM2.5 removal efficiency. The wind flow through the inflow air vent is 10 m3/hour and the air outlet of the machinery operates at 8 m3/hour. Determine if the outflow air vent air quality is within the local standard of 500 ug/m3. The factory has a volume of 200 m3. Assume the air inflow has a PM2.5 concentration of 0 ug/m3

A factory operates heavy machinery which emits pollutant air with a PM2.5 of 700 ug/m3
. The factory has inflow and outflow air vents and an air filter to assist with reducing the PM2.5 concentration of the outflowing air from the factory. The air purifier removes PM2.5 at a rate of 4 m3/hr and has a 80% PM2.5 removal efficiency. The wind flow through the inflow air vent is 10 m3/hour and the air outlet of the machinery operates at 8 m3/hour. Determine if the outflow air vent air quality is within the local standard of
500 ug/m3. The factory has a volume of 200 m3. Assume the air inflow has a PM2.5 concentration of 0
