Detention Time Calculator

Find how long fluid stays in a tank.

Calculated Output

Detention time 12

Detention time (days) 0.5

Formula: detention time = volume ÷ flow rate

Step-by-Step Breakdown

1. Values used:

2. Tank volume = 50,000 gal

3. Flow rate = 100,000 gal/day

5. Detention time = 12

6. Detention time = Tank volume / Flow rate = 50,000 / 100,000 = 0.5days

Did this calculator solve your problem today?

The math behind it

detention time = tank volume ÷ flow rate (consistent units); × 24 for hours.

50,000 gal ÷ 100,000 gal/day → 12 h.

Same as retention time?

Yes — hydraulic retention time is the same calculation.
