Pilots can use a "cabin altimeter" (also known as a cabin differential pressure gauge) to measure the difference between inside and outside pressure. [8] Keeping the cabin altitude below 8,000 ft (2,438 m) generally prevents significant hypoxia, altitude sickness, decompression sickness, and barotrauma. [9]
The Laplace pressure is the pressure difference between the inside and the outside of a curved surface that forms the boundary between two fluid regions. [1] The pressure difference is caused by the surface tension of the interface between liquid and gas, or between two immiscible liquids.

As a result, the windshield could no longer withstand the pressure difference between inside and outside the cockpit and burst off from the fuselage. In addition, the flight control problems were found to be caused by the cockpit door opening as designed to prevent a pressure difference between the cockpit and cabin.
Currently developed and commercialized tensiometers monitors the pressure needed to form a bubble, the pressure difference between inside and outside the bubble, the radius of the bubble, and the surface tension of the sample are calculated in one time and a data acquisition is carried out via PC control.
For the thin-walled assumption to be valid, the vessel must have a wall thickness of no more than about one-tenth (often cited as Diameter / t > 20) of its radius. [4] This allows for treating the wall as a surface, and subsequently using the Young–Laplace equation for estimating the hoop stress created by an internal pressure on a thin-walled cylindrical pressure vessel:
