Question

gas viscosity = 1.861598E-5 kg/m-s

|An electrostatic precipitator has collecting plates 3 m tall 1 m |long in the direction of flow. The spacing between the charging electrode and the collecting plate is 7.56 cm. The device is to |be used to collect particles having a dielectric constant of 4 and |an effective diameter of 4 Hm. The carrier gas (air at 25 °C) has |a velocity of 1.2 m/s. Calculate the collection efficiency for a charging voltage of (a) 10 kV, (b) 20kV, (c) 30kV, (d) 40kV |and (e) 50kV. Omit the Cunningham correction. @ Kc: Cunningham correction factor (Applied for particles with diameter
