A parallel plate type ESP used for indoor air cleaning to remove particles. The ESP is handling 100 m3/h of gas. The spacing between two plates is 10 cm and the plates are 1 m high and 1 m long. Assume the particles are pre-charged in an electric field strength of 100 kV/m and under ion concentration of 5x1013/m3 for 2 second before entering the ESP plates. To evaluate the minimum efficiency of the ESP, its efficiency for the particle having highest penetration (or lowest electrical mobility) is considered. Assume this particle size is 100 nm, and ε=5. What is the maximum charge can the 100 nm particle acquired in pre-charging zone?

A parallel plate type ESP used for indoor air cleaning to remove particles. The ESP is handling 100 m3/h of gas. The spacing between two plates is 10 cm and the plates are 1 m high and 1 m long. Assume the particles are pre-charged in an electric field strength of 100 kV/m and under ion concentration of 5x1013/m3 for 2 second before entering the ESP plates. To evaluate the minimum efficiency of the ESP, its efficiency for the particle having highest penetration (or lowest electrical mobility) is considered. Assume this particle size is 100 nm, and ε=5.
What is the maximum charge can the 100 nm particle acquired in pre-charging zone?
