Pressure print that page


Pressure is an effect that occurs when a force is applied on a surface. Pressure is the amount of force acting on a unit area. The symbol of pressure is P . [ 1 ] [ 2 ] [ edit ] Formula Conjugate variables of thermodynamics Pressure Volume ( Stress ) ( Strain ) Temperature

Pressure 4-5 print that page

Although often categorized under the alternative and nu metal genres popular at the time, Pressure 4-5, not wanting to be pigeonholed with current trends, insisted they were not metal but rather a "heavy rock band with introspective and somewhat intelligent lyrics" and "not chanting the | 2011/9/26 19:38:54

Pressure measurement print that page


Many techniques have been developed for the measurement of pressure and vacuum . Instruments used to measure pressure are called pressure gauges or vacuum gauges . A manometer could also be referring to a pressure measuring instrument , usually limited to measuring pressures near to

Pressure cooking print that page


Pressure is created at the beginning with boiling liquid, such as water, inside the closed pressure cooker and the trapped steam increases the internal pressure and temperature, which is maintained throughout cooking time. Pressure cookers may be referred to by several other names. An early

Pressure vessel print that page


A pressure vessel is a closed container designed to hold gases or liquids at a pressure substantially different from the ambient pressure . The pressure differential is dangerous and many fatal accidents have occurred in the history of their development and operation. Consequently, their

Pressure sensor print that page


A pressure sensor measures pressure , typically of gases or liquids . Pressure is an expression of the force required to stop a fluid from expanding, and is usually stated in terms of force per unit area. A pressure sensor usually acts as a transducer ; it generates a signal as a function

Partial pressure print that page

In a mixture of ideal gases , each gas has a partial pressure which is the pressure which the gas would have if it alone occupied the volume. [ 1 ] The total pressure of a gas mixture is the sum of the partial pressures of each individual gas in the mixture. In chemistry , the partial | 2011/7/7 2:38:06

Sound pressure print that page

The instantaneous sound pressure is the deviation from the local ambient pressure p 0 caused by a sound wave at a given location and given instant in time. The effective sound pressure is the root mean square of the instantaneous sound pressure over a given interval of time (or space | 2011/8/7 21:58:06

Vapor pressure print that page


The equilibrium vapor pressure is an indication of a liquid's evaporation rate. It relates to the tendency of particles to escape from the liquid (or a solid). A substance with a high vapor pressure at normal temperatures is often referred to as volatile . The vapor pressure of any substance

Atmospheric pressure print that page


The standard atmosphere (symbol: atm) is a unit of pressure and is defined as being equal to 101.325 kPa . [ 1 ] The following units are equivalent, but only to the number of decimal places displayed: 760 mmHg ( torr ), 29.92 inHg , 14.696 psi , 1013.25 millibars / hectopascal . One standard
