(a) The pressure inside an alveolus with a 2.00×10?4 - m
Chapter 11, Problem 55(choose chapter or problem)
(a) The pressure inside an alveolus with a \(2.00 \times 10^{-4}-\mathrm{m}\) radius is \(1.40 \times 10^{3} \mathbf{P a}\), due to its fluid-lined walls. Assuming the alveolus acts like a spherical bubble, what is the surface tension of the fluid?
(b) Identify the likely fluid. (You may need to extrapolate between values in Table \(11.3\).)

ANSWER:
Solution 55PE:
Step 1 of 3:-
The radius of the alveolus is, .
The inside pressure is, .
This is the gauge pressure inside the alveolus.
