Explanation:
Using Laplace's law of surface tension:
where:
P = pressure
T = surface tension
r = radius
In the longer alveoli with radius of 0.07 mm = ; we have:
P =
P =
In the smaller alveoli with radius 0.05 mm = ; we have:
P =
P =
The pressure difference can now be calculate as follows:
Pressure difference =
Pressure difference =
