The formula to calculate the Saturated Water Vapor Pressure (P) is:
\[ P = 0.61 \times e^{\left(\frac{18.68 - T}{234.5}\right) \times \left(\frac{T}{257.14 + T}\right)} \]
Where:
Water vapor pressure is the force exerted by water vapor molecules in the air. It represents the partial pressure of water vapor in a mixture of gases. When water evaporates, its molecules escape into the air, creating water vapor. As these molecules move around, they collide with each other and with other molecules in the air, exerting a certain amount of pressure.
Let's assume the following value for an example:
Using the formula:
\[ P = 0.61 \times e^{\left(\frac{18.68 - 25}{234.5}\right) \times \left(\frac{25}{257.14 + 25}\right)} \approx 3.16 \, \text{kPa} \]
The Saturated Water Vapor Pressure is approximately 3.16 kPa.
