Determine the terminal settling velocity of a particle having a density of 2540 kg/m3 and a diameter of 10 mm in water having a temperature of 10C. You may assume that the particle is a perfect sphere (shape factor = 1). What would be the settling velocity for the same particle if the water temperature decreased to 5C?

Compute the settling velocity for the following particles: very coarse sand ( diameter = 1.5 mm ) , (diameter=1.5 mm), medium sand (0.4 mm), very fine sand (0.075 mm), and clay (0.001 mm). Estimate the time for each particle to fall 6 in. in water. Assume: SG: coarse sand = 2.65, medium sand = 2.67, fine sand = 2.70, clay = 2.8 & water temperature = 60°F Note:The other solution on chegg is wrong.

1. Compare the terminal velocity of a 10 nanometer particle with a 100 nanometer particle. Which one “falls” through the air faster? What are the approximate speeds of both particles as they “fall?” Use Equation 2.1 on page 35 in your analysis. Also use Pg = 1.225 Kg/m3 and Pp = 1000 Kg/m3. 2. What is “fume fever?” 3. What are CCNs and how are they affected by nanoparticles? 4. Why is the amount of dimethyl sulfide (DMS) produced by...

(a) Calculate the settling velocity of glass spheres (density = 2467 kg/m3) having diameter as 1.5 mm in water. The slurry contains 65% by weight solid. Use Newton’s law. (b) Mixture of an ore (density 2000 kg/m3) and gangue (density 7000 kg/m3) is to be separated in a hydraulic elutriator. The mixture has following size distribution, which is valid for ore as well as gangue. Predict the upward velocity of water in elutriator so that entire ore is collected in...

Calculate the terminal velocity in free fall of a bowling ball (mass of 7.2 kg, diameter of 21.6 cm) and a basketball (mass of 0.51 kg, diameter of 23.85 cm). The bowling ball can be considered a smooth sphere (Cd = 0.1), while the basketball can be considered a rough sphere (Cd = 0.4). What would be the terminal velocity of the basketball if we considered it a smooth sphere?

Use the force balance Fd = Fg −Fb to derive a formula for the terminal settling (fall) speed vs of the particle. Simplify as far as possible (Hint: replace the particle mass with its density and volume, the latter then with a radius based description).
