What is the pressure inside an alveolus having a radius of 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: .
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.
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: .
The surface tension is given is: .
The surface tension is:
The pressure exerted in the bubble is .
A negative pressure of 25.0 atm can sometimes be achieved with the device in Figure 11.44 before the water separates. (a) To what height could such a negative gauge pressure raise water? (b) How much would a steel wire of the same diameter and length as this capillary stretch if suspended from above?
