Calculation of Settling Velocity of Spherical Grit Particles
Given Parameters:
- Radius of spherical grit particles (r) = 0.01 mm
- Specific gravity of spherical grit particles (SG) = 3.0
- Acceleration due to gravity (g) = 9.81 m/s2
- Density of liquid in settling chamber (ρ) = 1000 kg/m3
- Kinematic viscosity of liquid in settling chamber (ν) = 10^-6 m2/s
- Assuming laminar conditions
We can use the Stokes' Law equation to calculate the settling velocity of spherical grit particles in the given conditions.
Stokes' Law Equation: V = (2/9) * [(SG - 1) * g * r^2] / ν
Where,
- V = Settling velocity of spherical grit particles
- SG = Specific gravity of spherical grit particles
- g = Acceleration due to gravity
- r = Radius of spherical grit particles
- ν = Kinematic viscosity of liquid in settling chamber
Substituting the given values in the equation, we get:
V = (2/9) * [(3 - 1) * 9.81 * (0.01 * 10^-3)^2] / (10^-6) = 0.436 mm/s (approx.)
Therefore, the settling velocity of spherical grit particles in the given conditions is 0.436 mm/s (approx.).
Given Parameters:
- Radius of spherical grit particles (r) = 0.01 mm
- Specific gravity of spherical grit particles (SG) = 3.0
- Acceleration due to gravity (g) = 9.81 m/s2
- Density of liquid in settling chamber (ρ) = 1000 kg/m3
- Kinematic viscosity of liquid in settling chamber (ν) = 10^-6 m2/s
- Assuming laminar conditions
We can use the Stokes' Law equation to calculate the settling velocity of spherical grit particles in the given conditions.
Stokes' Law Equation: V = (2/9) * [(SG - 1) * g * r^2] / ν
Where,
- V = Settling velocity of spherical grit particles
- SG = Specific gravity of spherical grit particles
- g = Acceleration due to gravity
- r = Radius of spherical grit particles
- ν = Kinematic viscosity of liquid in settling chamber
Substituting the given values in the equation, we get:
V = (2/9) * [(3 - 1) * 9.81 * (0.01 * 10^-3)^2] / (10^-6) = 0.436 mm/s (approx.)
Therefore, the settling velocity of spherical grit particles in the given conditions is 0.436 mm/s (approx.).
