Air Inlet tempertun = 300°K; Exhaust pression = 1.0275 bal

Determine (1) The Sav • Scavenging ratio

(ii) The Scavenging efficiency 1111/ Trapping Efficiency.

Answer 1

Scavenging ratio:

The scavenging ratio, i.e. the concentration of a certain pollutant in precipitation divided by the concentration of the pollutant in air.
