Calculate Evaporation Rate







Formula

The formula to calculate the evaporation rate is:

\[ \text{gh} = (25 + 19v) \times A \times (X_s - X) \]

Where:

Example Calculation

Let's consider an example:

Using the formula to calculate the evaporation rate:

\[ \text{gh} = (25 + 19 \times 2) \times 10 \times (0.03 - 0.01) = (25 + 38) \times 10 \times 0.02 = 63 \times 10 \times 0.02 = 12.6 \text{ kg/h} \]

This demonstrates that with a velocity of 2 m/s, a water surface area of 10 m², a maximum humidity ratio of 0.03, and a current humidity ratio of 0.01, the evaporation rate is approximately 12.6 kg/h. ✅
