Short Answer

What is the pressure inside an alveolus having a radius of $2.50 \times 10^{- 4} m$ if the surface tension of the fluid-lined wall is the same as for soapy water? You may assume the pressure is the same as that created by a spherical bubble.

The pressure exerted in the bubble is obtained as: $592 P a$ .

Step 1: Conceptual Introduction

Fluid statics, often known as hydrostatics, is a branch of fluid mechanics that investigates the state of balance of a floating and submerged body, as well as the pressure in a fluid, or imposed by a fluid, on an immersed body.

Step 2: Given data

The tensions between molecules that cause a liquid's surface to compress to the lowest feasible surface area.

The radius r of the bubble is: $2.50 \times 10^{- 4} m$ .

The surface tension is given is: $0.03 N / m$ .

Step 3: Force per unit area acting on the soap bubble

The surface tension is:

$p = \frac{4 σ}{r} = \frac{4 (0.03 N / m)}{2.5 \times 10^{- 4} m} = 592 P a$

The pressure exerted in the bubble is $592 P a$ .
