Marine Watermaker Output Estimate
Estimate rated daily production and tank-fill time from your assumptions.
A QUICK WALKTHROUGH
How to use this tool
- Enter values in the stated units, then calculate.
Inputs and limits
Output: 0.000001–1,000,000,000 L/h; hours: 0–24/day; remaining tank and per-user consumption: 0–1,000,000,000; users: whole numbers 1–1,000,000,000. P (L/day) = q (L/h) × h (h/day); D (L/day) = n × c (L/person/day); net = P − D; fill (days) = remaining tank (L) ÷ net Floating-point results use up to 6 significant digits; rounding does not improve accuracy.
Scope
Assumes constant nameplate performance and daily demand, with no losses. An already full tank takes zero days; nonpositive net output cannot fill a nonempty tank. Excludes salinity, temperature, membrane condition, power limits and downtime. Does not assess potability, equipment design or safety.
GOOD TO KNOW
Common questions
Are these results a design or safety recommendation?
No. These are arithmetic estimates, not engineering design or safety advice. Inputs stay in this browser; nothing is uploaded or stored.
