The inside pressure of a typical champagne bottle is around 620 kilopascals (90 psi). The diameter of the opening is 18 millimetres (0.71 in), so there is a force of about 160 newtons (36 lb f) trying to push the cork out of the bottle. At the opening of the bottle, there is a lip that creates a stress concentration. On the vertical seam of the ...
In a nozzle or other constriction, the discharge coefficient (also known as coefficient of discharge or efflux coefficient) is the ratio of the actual discharge to the ideal discharge, [1] i.e., the ratio of the mass flow rate at the discharge end of the nozzle to that of an ideal nozzle which expands an identical working fluid from the same initial conditions to the same exit pressures.
A self-pressurising dewar (silver) being filled with liquid nitrogen from a larger storage tank (white). A cryogenic storage dewar (or simply dewar) is a specialised type of vacuum flask used for storing cryogens (such as liquid nitrogen or liquid helium), whose boiling points are much lower than room temperature.

Unlike a lid or bottle cap, which encloses a container from the outside without displacing the inner volume, a bung is partially or wholly inserted inside the container to act as a seal. A bung can be defined as "a plug or closure used to close an opening in a drum or barrel.
The autoignition temperature or self-ignition temperature, often called spontaneous ignition temperature or minimum ignition temperature (or shortly ignition temperature) and formerly also known as kindling point, of a substance is the lowest temperature at which it spontaneously ignites in a normal atmosphere without an external source of ignition, such as a flame or spark.

Microwave digestion is a chemical technique used to decompose sample material into a solution suitable for quantitative elemental analysis. [1] It is commonly used to prepare samples for analysis using inductively coupled plasma mass spectrometry (ICP-MS) , atomic absorption spectroscopy , and atomic emission spectroscopy (including ICP-AES ).
