1. What is Displacement Velocity?

Displacement Velocity refers to the velocity associated with the displacement of an object in fluid dynamics, particularly in sedimentation and particle transport applications.

2. How Does the Calculator Work?

The calculator uses the displacement velocity formula:

Where:

• \( v_d \) — Displacement Velocity (m/s)
• \( V_s \) — Settling Velocity (m/s)

Explanation: The formula establishes a direct proportional relationship between displacement velocity and settling velocity with a constant multiplier of 18.

3. Importance of Displacement Velocity Calculation

Details: Accurate displacement velocity calculation is crucial for understanding particle transport in fluids, sedimentation processes, and designing separation systems in various engineering applications.

4. Using the Calculator

Tips: Enter settling velocity in m/s. The value must be valid (greater than 0). The calculator will compute the corresponding displacement velocity.

5. Frequently Asked Questions (FAQ)

Q1: What is the relationship between displacement velocity and settling velocity?
A: Displacement velocity is directly proportional to settling velocity with a constant factor of 18, meaning displacement velocity is always 18 times the settling velocity.

Q2: In what applications is this formula commonly used?
A: This formula is commonly used in sedimentation tanks, water treatment plants, and particle separation systems where understanding particle movement in fluids is essential.

Q3: What units should be used for input values?
A: Both settling velocity and displacement velocity are typically measured in meters per second (m/s) for consistency in fluid dynamics calculations.

Q4: Are there limitations to this formula?
A: This simplified formula assumes ideal conditions and may need adjustments for specific fluid properties, particle shapes, or non-standard environmental conditions.

Q5: Can this formula be used for all types of particles?
A: While generally applicable, the formula works best for spherical particles in Newtonian fluids. Irregular shapes or non-Newtonian fluids may require additional considerations.
