The discharge rate formula calculates the flow rate of liquid through a sedimentation tank based on settling velocity and tank dimensions. It provides an accurate assessment of the tank's capacity and efficiency in separating particles from the fluid.
The calculator uses the discharge rate formula:
Where:
Explanation: The formula multiplies the settling velocity by the cross-sectional area (length × width) to determine the volumetric flow rate through the sedimentation tank.
Details: Accurate discharge rate calculation is crucial for designing efficient sedimentation tanks, optimizing treatment processes, and ensuring proper particle removal in water and wastewater treatment systems.
Tips: Enter settling velocity in m/s, length and width in meters. All values must be positive numbers greater than zero for accurate calculation.
Q1: What is settling velocity?
A: Settling velocity refers to the terminal velocity at which particles settle in still fluid under gravity, measured in m/s.
Q2: How does tank dimension affect discharge rate?
A: Larger tank dimensions (length and width) increase the cross-sectional area, resulting in higher discharge rates for the same settling velocity.
Q3: What are typical values for settling velocity?
A: Settling velocity varies by particle size and density, typically ranging from 0.001 to 0.1 m/s for most sedimentation applications.
Q4: Can this formula be used for circular tanks?
A: This formula is specifically for rectangular sedimentation tanks. For circular tanks, different formulas involving radius and cross-sectional area are used.
Q5: How accurate is this calculation for real-world applications?
A: The formula provides theoretical maximum discharge. Real-world efficiency may be lower due to factors like turbulence, inlet/outlet conditions, and particle characteristics.
