A 20 m³/s air stream from a cement kiln carries 120 mg/m³ of particulate matter to an electrostatic precipitator for air-quality control.
The ESP has four plates, each measuring 8.0 m by 5.0 m.
The particles have a drift velocity of 0.15 m/s.
Estimate the particle concentration in the ESP exhaust (mg/m³).

Particle migration velocity i.e velocity through which particle migrated towards plate after charged (Vpm)=0.15m/s,
Height of Plate= 8.0m,
Length of Plate=5.0m
Total number of plate= 4
Area of collection of particulate matter = 4x2x8.00x5.00=320.00m²...
