Kelvin Equation Vapor Pressure Calculator
Calculate the vapor pressure over a curved surface using the Kelvin Equation:
\[
\ln\left(\frac{p}{p_0}\right) = \frac{2\gamma V_m}{R\,T\,r}
\]
* Enter the flat surface vapor pressure \( p_0 \) (Pa), surface tension \( \gamma \) (N/m), molar volume \( V_m \) (m³/mol), radius \( r \) (m), and temperature \( T \) (K).
Step 1: Enter Parameters
Example: 101325 Pa (1 atm)
Example: 0.072 N/m (for water)
Example: 1.8e-5 m³/mol
Example: 1e-6 m
Example: 298 K (25°C)
