The formula to calculate the Pressure Change (Δpnew) is:
\[ \Delta p_{new} = \frac{4 \cdot \sigma}{d} \]
Pressure change new is the difference between the pressure inside the liquid droplet and atmospheric pressure. Surface tension is a physical property of liquids, in which the molecules are drawn onto every side. Diameter of droplet is the length of the longest chord of the liquid droplet.
Let's assume the following values:
Using the formula:
\[ \Delta p_{new} = \frac{4 \cdot 72.75}{1.21} \approx 240.495867768595 \]
The Pressure Change is approximately 240.495867768595 Pa.
