3. Flue gas stream of 4xy m3/s (x and y are the last two digits of your Sheridan ID number; for example, if the last two digits of your ID number are 78, your gas flow rate is 478 m3/s) is to be treated by an electrostatic precipitator to remove fly ash. a. What plate area is required to remove 1.0 um particles with 80% efficiency if the ash drift velocity is w = 2.57x105 dp? (3 marks) b. Calculate also plate area required to achieve 85%, 90%, and 95 % removal efficiencies of the same particles. (3 marks) c. Calculate % of the plate area increase required to increase removal efficiency from 80% to 85%. Also, calculate % of the plate area increase required to increase removal efficiency from 85% to 90% and from 90% to 95%. Discuss your results. (3 marks) d. Draw a graph of plate area vs removal efficiency. (2 marks)
