Estimate make-up water needed by a vertical farm from plant count, daily use per plant, recirculation recovery, system losses, and the planning period. The result separates crop demand from recoverable flow so reservoir and supply planning are easier.
Percent inputs are divided by 100 in the calculation. Unit conversions are shown in the results where applicable.
Make-up water is the fresh supply needed after applying the entered recovery rate and additional loss allowance. It supports storage and utility planning rather than precise irrigation scheduling.
Measure condensate recovery, leaks, cleaning water, and crop-specific demand on site; they can change substantially with climate and growth stage.
For 4,000 plants using 0.35 L/day, 85% recovery, 5% additional loss, and 30 days, make-up water is 220.5 L/day or 6,615 L total.
Yes, as a scenario estimate. Replace the defaults with measured operating data and keep a separate contingency for variability.
Calculate shorter periods with consistent assumptions, then add the period results. This is more reliable than using one blended value.
Use the most likely measured value for the base case, then recalculate with conservative and optimistic assumptions to see the planning range.
Equipment performance, biological variation, environmental conditions, measurement error, and downtime can all move the actual result.
No. The calculation runs in your browser and this page does not need to send the entered values to a server.
