4- In an electrostatic precipitator (ESP) system, dielectric constant is 6 and local field strength is 400kV/m. Collecting area to flowrate ratio is found to be 0.05s/m. Calculate the individual and overall efficiency of the ESP (in \%) for the particle data given in Table 2 below by using the mixed-flow equation (0=8.851012C/vm and :1.8105kg/ms). Table 2. PM data for ESP. 4- In an electrostatic precipitator (ESP) system, dielectric constant is 6 and local field strength is 400kV/m. Collecting area to flowrate ratio is found to be 0.05s/m.
