Evaporation Rate Calculator
Calculate evaporation rate using measured mass loss and duration.
How to Use This Calculator
1
Measure mass loss
Record initial and final mass; compute the difference.
2
Measure time interval
Duration over which mass decreased.
3
Calculate rate
Rate = Δm / Δt in kg/s. Convert to kg/h by ×3600.
Formula
Evaporation rate = Δm / Δt
Example: Δm = 0.1 kg over 1 h (3600 s) → 2.78×10⁻⁵ kg/s
About Evaporation Rate
Rate depends on temperature, humidity, surface area, airflow, and liquid properties.
Frequently Asked Questions
Can this estimate theoretical rates?
This tool uses measurement-based rate. Theoretical models require more parameters.
Other units?
Multiply kg/s by 3600 for kg/h; by 1000 for g/s, etc.
