v_s = (g/18)*(G-1)*((D_p)^2/ν)
This formula uses 5 Variables

Variables Used

Settling Velocity - (Measured in Meter per Second) - Settling velocity is defined as the terminal velocity of a particle in still fluid.
Acceleration due to Gravity - (Measured in Meter per Square Second) - Acceleration due to Gravity is acceleration gained by an object because of gravitational force.
Specific gravity of sediment - Specific gravity of sediment is the ratio of density of sediment to density of standard substance.
Diameter of Partical - (Measured in Meter) - Diameter of Partical is a straight line passing from side to side through the center of a partical, especially a circle or sphere.
Kinematic Viscosity - (Measured in Square Meter per Second) - The kinematic Viscosity is an atmospheric variable defined as the ratio between the dynamic viscosity μ and the density ρ of the fluid.

STEP 1: Convert Input(s) to Base Unit

Acceleration due to Gravity: 9.8 Meter per Square Second --> 9.8 Meter per Square Second No Conversion Required
Specific gravity of sediment: 1.3 --> No Conversion Required
Diameter of Partical: 0.01 Meter --> 0.01 Meter No Conversion Required
Kinematic Viscosity: 7.25 Stokes --> 0.000725 Square Meter per Second (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

v_s = (g/18)*(G-1)*((D_p)^2/ν) --> (9.8/18)*(1.3-1)*((0.01)^2/0.000725)

Evaluating ... ...

v_s = 0.0225287356321839

STEP 3: Convert Result to Output's Unit

0.0225287356321839 Meter per Second --> No Conversion Required

FINAL ANSWER

0.0225287356321839 ≈ 0.022529 Meter per Second <-- Settling Velocity
