Density (kg/m³) Water = 1,000 Corn syrup = 1,408 3 mm glass bead = 2,430 Viscosity (kg/s\cdot m) Water = 0.890 \times 10^{-3} Corn syrup = 7

          Density
(kg/m³)
Water = 1,000
Corn syrup = 1,408
3 mm glass bead = 2,430
Viscosity
(kg/s\cdot m)
Water = 0.890 \times 10^{-3}
Corn syrup = 7

Density
(kg/m³)
Water = 1,000
Corn syrup = 1,408
3 mm glass bead = 2,430
Viscosity
(kg/s·m)
Water = 0.890 ×10^-3
Corn syrup = 7

Step 1

Stokes' law states that the settling velocity (v) of a particle is given by the equation: v = (2/9) * (g * r^2 * (ρp - ρf)) / η where: - v is the settling velocity - g is the acceleration due to gravity (approximately 9.8 m/s^2) - r is the radius of the Show more…

Students performed discrete particle settling tests using a 3 mm diameter glass bead in a 15 cm tall graduated cylinder, with either water or corn syrup as the fluid. Using Stokes' law and the data in the table below, demonstrate why his students were able to measure the particle settling velocity using corn syrup but not water when the settling test was performed under these conditions: Density (kg/m^3) Viscosity (kg/s-m) Water = 1,000 Water = 0.890 x 10^-3 Corn syrup = 7 Corn syrup = 1,408 3 mm glass bead = 2,430
