Formula and working
Water (L/day) = airflow(L/s) × Δhumidityratio × 86400 ÷ 1000 × airDensity
- 1
Collect the inputs
Airflow rate = 200 CFM; Inlet humidity ratio = 0.014 kg/kg; Outlet humidity ratio = 0.008 kg/kg; Operating hours = 12 hr/day

Apply the formula
Water (L/day) = airflow(L/s) × Δhumidityratio × 86400 ÷ 1000 × airDensity
- 3
Result
Daily water extraction = 29.36 L/day
