Calculate Evaporation Potential (EP)





Formula

The formula to calculate the evaporation potential (EP) is:

\[ EP = (25 + 19 \cdot WS) \cdot (0.5 + 0.54 \cdot T) \cdot (1 - \frac{RH}{100}) \]

Where:

Example

Let's say the temperature (\( T \)) is 30°C, the relative humidity (\( RH \)) is 50%, and the wind speed (\( WS \)) is 5 m/s. Using the formula:

\[ EP = (25 + 19 \cdot 5) \cdot (0.5 + 0.54 \cdot 30) \cdot (1 - \frac{50}{100}) \]

We get:

\[ EP = (25 + 95) \cdot (0.5 + 16.2) \cdot 0.5 = 120 \cdot 16.7 \cdot 0.5 = 1002 \text{ mm/day} \]

So, the evaporation potential (\( EP \)) is 1002 mm/day.

What is Evaporation Potential?

Evaporation potential is a measure of the ability of the atmosphere to remove water from the surface through the process of evaporation. It is influenced by factors such as temperature, humidity, and wind speed. Understanding evaporation potential is important for water resource management, agriculture, and climate studies.
