A circular primary clarifier processes an average flow of 5005 m3/d of...
Given data:
Average flow of municipal wastewater = 5005 m3/d
Overflow rate = 35 m3/m2/d
To calculate the diameter of the clarifier, we can use the formula:
Overflow rate = Flow rate / (π * Radius^2)
Where,
Flow rate = Average flow of municipal wastewater = 5005 m3/d
Overflow rate = 35 m3/m2/d
Radius = Diameter / 2
Let's solve the equation step by step:
1. Calculate the flow rate:
Flow rate = Average flow of municipal wastewater = 5005 m3/d
2. Calculate the radius:
Overflow rate = Flow rate / (π * Radius^2)
35 = 5005 / (π * Radius^2)
35 * (π * Radius^2) = 5005
π * Radius^2 = 5005 / 35
π * Radius^2 = 143
Radius^2 = 143 / π
Radius^2 ≈ 45.534
Taking the square root on both sides:
Radius ≈ √45.534
Radius ≈ 6.75 m
3. Calculate the diameter:
Diameter = 2 * Radius
Diameter ≈ 2 * 6.75
Diameter ≈ 13.5 m
Therefore, the diameter of the clarifier should be approximately 13.5 m. Hence, the correct answer is option D.
Average flow of municipal wastewater = 5005 m3/d
Overflow rate = 35 m3/m2/d
To calculate the diameter of the clarifier, we can use the formula:
Overflow rate = Flow rate / (π * Radius^2)
Where,
Flow rate = Average flow of municipal wastewater = 5005 m3/d
Overflow rate = 35 m3/m2/d
Radius = Diameter / 2
Let's solve the equation step by step:
1. Calculate the flow rate:
Flow rate = Average flow of municipal wastewater = 5005 m3/d
2. Calculate the radius:
Overflow rate = Flow rate / (π * Radius^2)
35 = 5005 / (π * Radius^2)
35 * (π * Radius^2) = 5005
π * Radius^2 = 5005 / 35
π * Radius^2 = 143
Radius^2 = 143 / π
Radius^2 ≈ 45.534
Taking the square root on both sides:
Radius ≈ √45.534
Radius ≈ 6.75 m
3. Calculate the diameter:
Diameter = 2 * Radius
Diameter ≈ 2 * 6.75
Diameter ≈ 13.5 m
Therefore, the diameter of the clarifier should be approximately 13.5 m. Hence, the correct answer is option D.
