Answer #1

Answer.

No matter what size of dust , it always a problematic issue to human health .

Dust particles mainly cause the health effects associated with lungs and other respiratory diseases.

Larger particulate matter are easy to get trap to upper respiratory tract and smaller one may get deeper into the lungs causing severe damage to respiratory system. Particles of size less than 2.5 um causes severe health problems .

Particles size less than 0.2 um are the smallest one and can reach deeper into the lungs upto alveli air sacs may cause harmful effects to the lungs and Brain.

Design a horizontal flow grit chamber to remove grit (SG = 2.5) of size 0.2 mm and larger for a water temperature of 20°C. The average daily flow rate is 2.227 MGD. The chamber should be designed to treat the peak hourly flow. The flow peaking factor (i.e., ratio of peak hourly to average daily) is 2.5. Use a ratio of tank depth to width of 1.25. Use a safety factor of 1.35 (i.e., Adplan = Aplan ́ 1.35). Make...
