Extracted text: Civil Engineering An electrostatic precipitator is being designed to operate at an efficiency of 97%. Using the modified Deutsch-Anderson equation, calculate the area of cach plate for exponents of 0.4, 0.6 and 0.7 for the modified Deutsch equation. The following information is given: Volumetric flow rate 10,000 acfm (evenly distributed) Drift velocity = 0.5 ft/s Plate spacing = 6 in Number of ducts (passages) = 20
