Question

Find the minimum length of a collecting electrode for a single-stage wire–plate-type precipitator with a 30 cm plate-to-plate spacing and an applied voltage of 75,000 V.

Air velocity through the precipitator is 1 m/s and the minimum particle diameter is 900 nm

Data:

K0 = 8.85 x 10-12 C2 / N m2

μ = 1.8 x 10-5 Pa·s at 25oC

P = 1
