Laser fume from plastics, metals and wood comprises harmful particulate matter. This industrial dust needs to be extracted from air when an operator is engaged in the laser cutting process. (i) Explain how both a cyclone and an electrostatic precipitator work, and then, giving your reasons, rationalise why, out of the two technologies, you would recommend using electrostatic precipitation to be used for extracting dust during laser cutting of plastics. (6 marks) (ii) The efficiency (E) of an electrostatic precipitator...

ENVIRONMENTAL ENGINEERING, please show all work and clearly circle
your answer.
A settling tank is being designed to remove suspended particles through Type 1 settling. The density of the particle is 1045 kg/m23 and the density of the water is 1020 kg/m2. The diameter of the particles is 0.2 mm and the temperature is 25* C. Assuming laminar conditions, find the settling velocity, vi, for the particles. If the overflow rate is 65 m2/d m2, what is the percentage of...

Please answer all three parts and show work. Thank you!
1. An ideal gas assumes molecules are point particles and do not interact with each other. In reality, molecules occupy space! To correct for this, the ideal gas equation of state is adjusted to take the volume occupied by the molecules into account for a real gas: PV = nRT or P = nRTV is modified to P = nRT/(V-nb) (IDEAL GAS) (REAL GAS Where "b" is related to the...
