- For the first drop: R1=D12=1 cm2=0.5 cm - For the second drop: R2=D22=1.5 cm2=0.75 cm 3. Understand the Formula for Excess Pressure: - The excess pressure (ΔP) inside a liquid drop is given by the formula:
Step 2: Use the formula for excess pressure The excess pressurePinside a droplet due to surface tension is given by: P=2TR whereTis the surface tension of water, given asT=72×10−3N/m. Step 3: Calculate the excess pressure inside and outside the raindrop ...
places the liquid near the center of the body in a state of hydrostatic tension. The time required for liquid to flow from the surface to the interior is described byDarcy's law, and thus depends on parameters such as the particle size, particle packing density, differential liquid pressure,...
<p>To solve the problem, we need to evaluate the density of the liquid that balances the excess pressure inside a soap bubble. Here are the steps to arrive at the solution:</p><p><strong>Step 1: Understand the relationship between excess pressure and sur

In Figure 8a, when the air temperature is very low, there is no liquid raindrop and the sub-cloud evaporation can be neglected for the cold environment. In Figure 8b, small precipitation can be widely seen, although larger precipitation corresponds the low evaporation. For the relative humidity...
