Depth of tank
Surface area of tank
Both depth and surface area of tank
None of the above
Answer is Right!
Answer is Wrong!
The correct answer is: C. Both depth and surface area of tank.
The settling velocity of a particle in a sedimentation tank depends on the following factors:
- Particle size: The larger the particle, the faster it will settle.
- Particle density: The denser the particle, the faster it will settle.
- Fluid viscosity: The higher the viscosity of the fluid, the slower the particle will settle.
- Gravity: The higher the acceleration due to gravity, the faster the particle will settle.
- Tank depth: The deeper the tank, the longer the particle will have to fall and the faster it will settle.
- Tank surface area: The larger the surface area of the tank, the more particles can settle at the same time.
Therefore, the settling velocity of a particle in a sedimentation tank depends on both the depth and surface area of the tank.
- Option A: Depth of tank: The depth of the tank affects the settling velocity of a particle by affecting the time it takes for the particle to fall to the bottom of the tank. The deeper the tank, the longer the particle will have to fall and the faster it will settle.
- Option B: Surface area of tank: The surface area of the tank affects the settling velocity of a particle by affecting the number of particles that can settle at the same time. The larger the surface area of the tank, the more particles can settle at the same time.
- Option C: Both depth and surface area of tank: The settling velocity of a particle in a sedimentation tank depends on both the depth and surface area of the tank. The deeper the tank, the longer the particle will have to fall and the faster it will settle. The larger the surface area of the tank, the more particles can settle at the same time.
- Option D: None of the above: The settling velocity of a particle in a sedimentation tank depends on both the depth and surface area of the tank.
