Internal pressure is a measure of how the internal energy of a system changes when it expands or contracts at constant temperature. It has the same dimensions...

: 445  Gauge pressure (also spelled gage pressure) is the pressure relative to the ambient pressure. Various units are used to express pressure. Some of these...

steam produced from the boiling liquid. This is used to raise the internal pressure up to one atmosphere above ambient and gives higher cooking temperatures...

A pressure vessel is a container designed to hold gases or liquids at a pressure substantially different from the ambient pressure. Construction methods...

equation for estimating the hoop stress created by an internal pressure on a thin-walled cylindrical pressure vessel: σ θ = P r t   {\displaystyle \sigma _{\theta...

maintaining the internal pressure, thereby preventing it from going flat. The carbonated beverage is dispensed using the internal pressure of the bottle...

(3) in (1) gives the above expression. The internal pressure is defined as a partial derivative of the internal energy with respect to the volume at constant...

Atmospheric pressure, also known as air pressure or barometric pressure (after the barometer), is the pressure within the atmosphere of Earth. The standard...

Blood pressure (BP) is the pressure of circulating blood against the walls of blood vessels. Most of this pressure results from the heart pumping blood...

helps maintain pressure when stratocruising and protects the aircraft from bursting due to the higher internal pressure. Aft pressure bulkheads can either...

sealed to hold an internal pressure significantly higher than ambient pressure, a pressurised gas system to control the internal pressure, and a supply of...

(symbol: Pa) is the unit of pressure in the International System of Units (SI). It is also used to quantify internal pressure, stress, Young's modulus,...

light and better color rendition. Mercury vapor lights operate at an internal pressure of around one atmosphere and require special fixtures, as well as...

open-bottomed wet bell and the closed bell, which can maintain an internal pressure greater than the external ambient. Diving bells are usually suspended...

decrease in (the sum of) its potential energy (including the static pressure) and internal energy. If the fluid is flowing out of a reservoir, the sum of all...

a higher internal pressure when fired than is standard for ammunition of its caliber (see internal ballistics), but less than the pressures generated...

a result, a person who is bleeding internally may initially have a normal blood pressure. When the blood pressure falls below the normal range, this is...

high-pressure pure oxygen cabin atmosphere. Rescue was prevented by the plug door hatch, which could not be opened against the internal pressure of the...

pressure vessel (thick walled) is subjected to enormous pressure, causing internal portions of the part to yield plastically, resulting in internal compressive...

A boiler stay is an internal structural element of a boiler. Where the shell of a boiler or other pressure vessel is made of cylindrical or (part) spherical...

resembles a suit of armour, with elaborate pressure joints to allow articulation while maintaining an internal pressure of one atmosphere. An ADS can enable...

a bladder to form the complete volleyball. A valve permits the internal air pressure to be adjusted. In a break from the traditional construction, in...

simulated internal pressure of a launch. Joint rotation, which occurred when the tang and clevis bent away from each other, reduced the pressure on the O-rings...

pressurized such that the internal pressure equals or exceeds any external pressure being applied to the structure (i.e. wind pressure). The structure does...

A hydraulic accumulator is a pressure storage reservoir in which an incompressible hydraulic fluid is held under pressure that is applied by an external...

high blood pressure, is a long-term medical condition in which the blood pressure in the arteries is persistently elevated. High blood pressure usually does...

The jugular venous pressure (JVP, sometimes referred to as jugular venous pulse) is the indirectly observed pressure over the venous system via visualization...

working fluid flow circuit. In an internal combustion engine, the expansion of the high-temperature and high-pressure gases produced by combustion applies...

energy (i.e., internal energy). Since the thermal energy cannot be converted back to hydraulic energy, the fluid experiences a drop in pressure, as is required...

was much higher than the earlier paper construction. Thus a greater internal pressure was possible, with a resultant greater thrust of the propulsive jet...
