Drift Velocity of Dispersed Particle Formula:
| From: | To: |
The Drift Velocity of Dispersed Particle is defined as the average velocity attained by charged particles, such as electrons, in a material due to an electric field. It represents the net motion of charged particles under the influence of an electric field.
The calculator uses the drift velocity formula:
Where:
Explanation: The drift velocity is directly proportional to both the electrophoretic mobility of the particle and the intensity of the applied electric field.
Details: Calculating drift velocity is crucial for understanding particle behavior in electrophoresis, designing separation systems, and analyzing charged particle motion in various scientific and industrial applications.
Tips: Enter electrophoretic mobility in m²/V·s and electric field intensity in V/m. Both values must be positive numbers greater than zero for accurate calculation.
Q1: What factors affect electrophoretic mobility?
A: Electrophoretic mobility depends on particle charge, size, shape, and the properties of the surrounding medium.
Q2: How does temperature affect drift velocity?
A: Temperature affects viscosity of the medium, which in turn influences electrophoretic mobility and thus drift velocity.
Q3: What are typical values for electrophoretic mobility?
A: Mobility values vary widely depending on the particle type, ranging from 10⁻⁹ to 10⁻⁷ m²/V·s for various biological and synthetic particles.
Q4: Can this formula be used for all charged particles?
A: This formula applies to particles where the electrophoretic mobility is known and the electric field is uniform.
Q5: What units should be used for accurate calculations?
A: Use SI units: meters per second (m/s) for velocity, square meters per volt-second (m²/V·s) for mobility, and volts per meter (V/m) for electric field intensity.
