Question

Problem 1. (PM terminal settling velocity) Calculate terminal settling velocity (V) values for ammonium sulfate ((NH4)2SO4) particles versus particle diameter (d) at: 20°C and 760 mm Hg for dry air. Particle diameter ranges from 0.001 μm ≤d₂ ≤ 10 um. Plot Ve versus da for the described conditions in a plot with Vte on the ordinate and d on the abscissa. Use log scales for both axes. | Solution hints: Follow the steps in example class worksheet problem 2 (Wednesday-Week 4). Calculate Vi by assuming the gas flow is in Stokes region and particles are spherical. Check Stokes region assumption by calculating the particle Reynolds Number (Rep).
