1. What is Discharge Given Settling Velocity?

Discharge entering basin given settling velocity is the volumetric flow rate of water that enters a sedimentation basin, calculated based on the settling velocity of particles in the fluid.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( Q_s \) — Discharge entering basin (m³/s)
• \( v_s \) — Settling velocity of particles (m/s)
• \( w \) — Width of the basin (m)
• \( L \) — Length of the basin (m)

Explanation: This formula calculates the discharge rate based on the settling characteristics of particles and the physical dimensions of the sedimentation basin.

3. Importance of Discharge Calculation

Details: Accurate discharge calculation is crucial for designing efficient sedimentation basins, ensuring proper particle removal, and optimizing water treatment processes.

4. Using the Calculator

Tips: Enter settling velocity in m/s, width and length in meters. All values must be positive numbers greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: What is settling velocity?
A: Settling velocity is defined as the terminal velocity of a particle in still fluid, which determines how quickly particles settle in a sedimentation basin.

Q2: Why is the 100/70 factor used in the formula?
A: This factor accounts for the efficiency and design parameters of typical sedimentation basins in water treatment processes.

Q3: What are typical values for basin dimensions?
A: Sedimentation basin dimensions vary based on treatment capacity, but typical widths range from 3-10 meters and lengths from 10-50 meters.

Q4: How does particle size affect settling velocity?
A: Larger particles have higher settling velocities due to greater mass, while smaller particles settle more slowly and may require additional treatment.

Q5: Can this formula be used for all types of sedimentation basins?
A: This formula is specifically designed for rectangular sedimentation basins with uniform flow conditions. Other basin shapes may require different calculations.
