?uestion 3: Settling Tank Performance A rectangular primary settling tank in a wastewater treatment plant is 20 m long × 10 m wide x 3 m deep. The solids (particles) present in the wastewater have a uniform density of 1010 kg/m3 and can be assumed to be spherical. For a wastewater flow rate of 10,000 m'/d and a water temperature of 10 °C, calculate: a) The size of the smallest particle that is completely (100%) removed b) The percentage of...

You are hired to design a rectangular sedimentation tank (length to width ratio = 3:1 and detention time ~ 2 h) for a new water treatment plant (flow rate: 0.04 m/s; temperature: 20 ). Suspended particles can be removed when the overflow rate is higher than the settling velocities of particles. You have finished characterizing the influent particles (assuming all of them are spherical) and obtained the following results: Particle diameter (m) Particle density (kg/m) Percentile 50 1.4 x 10...

You are hired to design a rectangular sedimentation tank (length to width ratio = 3:1 and detention time ~ 2 h) for a new water treatment plant (flow rate: 0.04 m3/s; temperature: 20 ℃). Suspended particles can be removed when the overflow rate is higher than the settling velocities of particles. You have finished characterizing the influent particles (assuming all of them are spherical) and obtained the following results: Particle diameter (m) Particle density (kg/m3) Percentile 50 1.4 x 103...

Problem 2 (20 points) You are hired to design a rectangular sedimentation tank (length to width ratio = 3:1 and detention time 2 h) for a new water treatment plant (flow rate: 0.04 m/s; temperature: 20 °C). Suspended particles can be removed when the overflow rate is higher than the settling velocities of particles. You have finished characterizing the influent particles (assuming all of them are spherical) and obtained the following results: Percentile Particle diameter (um) > 50 > 60...

4. A rectangular tank water (width 14.0m, length 14.0m, and height 20 m) is filled with water and open to the atmosphere. The water level in the tank is 1 m below the top of the tank. This tank sits upon a platform of height h. If the water tank is plugged at the bottom so no water is flowing, what is the resultant force exerted by the water on the bottom face of the container? What is the resultant...
