Clarifier Hydraulic Detention Time
Easydetention time
A clarifier holds 1,200 m³ and treats a flow of 0.10 m³/s. The hydraulic detention time is most nearly:
- A1.67 h
- B2.00 h
- C200.00 h
- D3.33 h
Show solutionHide solution
Answer: D. 3.33 h
Equation: hydraulic detention time t = V/Q. Values: V = 1,200 m³, Q = 0.10 m³/s. Step 1: t = 1,200/0.10 = 12,000 s. Step 2: 12,000/3,600 = 3.33 h. 200 h reports minutes as hours; 1.67 h halves it; 2.00 h multiplies V by Q.
