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, basin width, and basin length.
The calculator uses the formula:
Where:
Explanation: The formula calculates the volumetric flow rate by multiplying the settling velocity by the cross-sectional area of the basin (width × length).
Details: Accurate discharge calculation is crucial for designing sedimentation basins, ensuring proper treatment capacity, and optimizing particle removal efficiency in water treatment processes.
Tips: Enter settling velocity in m/s, width in meters, and length in meters. All values must be positive numbers greater than zero.
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 basin geometry important?
A: The width and length of the basin determine the surface area available for particle settlement, which directly affects the treatment efficiency.
Q3: What are typical values for settling velocity?
A: Settling velocity varies depending on particle size and density, typically ranging from 0.1 to 10 mm/s for most suspended solids in water treatment.
Q4: How does discharge affect sedimentation efficiency?
A: Higher discharge rates may reduce sedimentation efficiency as particles have less time to settle, while lower rates allow for better particle removal.
Q5: Can this formula be used for all types of sedimentation basins?
A: This formula is primarily used for rectangular sedimentation basins. Different basin geometries may require modified calculations.
