Constant Pressure

Some articles on constant pressure, constant, pressure, pressures:

George Brayton - Brayton's Ready Motor
... so that the fuel/air mixture burns progressively at constant pressure as it is transferred from the compressor cylinder and reservoir to the working cylinder ... The principle was referred to as constant pressure combustion, and had been attempted without success by Sir William Siemens c1861 using a 4-cylinder engine with separate combustion chamber ... Brayton not only achieved success in making the constant pressure cycle work, but he also made and marketed a commercial product ...
Heat Capacity Ratio
... ratio or adiabatic index or ratio of specific heats, is the ratio of the heat capacity at constant pressure to heat capacity at constant volume ... Suffix and refer to constant pressure and constant volume conditions respectively ... The pressure inside is equal to the outside air pressure ...
Strength (explosive)
... from its explosion, when expanded adiabatically from its original volume, until its pressure is reduced to atmospheric pressure and its temperature to 15°C ... therefore the total quantity of heat given off at constant volume when expressed in equivalent work units and is a measure of the strength of the explosive ... unconfined, as in the open air where the pressure (atmospheric) is constant the second, confined, as in a closed chamber where the volume is constant ...
Standard Enthalpy Of Reaction
... evolved in the transformation of the reactants at a given temperature and pressure into the products at the same temperature and pressure ... Enthalpy of a reaction at constant pressure and at a constant volume Enthalpy of a reaction depends upon the conditions under which the reaction is carried out ... (a) Constant volume (b) Constant pressure The magnitudes of the enthalpy changes in these two conditions are different ...
Metrology, The Measurement of Heat Capacity
... The heat capacity of most systems is not a constant ... on temperature itself, as well as on the pressure and the volume of the system, and the ways in which pressures and volumes have been allowed to change while the system has ... The reason for this is that pressure-volume work done to the system raises its temperature by a mechanism other than heating, while pressure-volume work done by the system absorbs heat without raising the system's ...

Famous quotes containing the words pressure and/or constant:

    Amid the pressure of great events, a general principle gives no help.
    Georg Wilhelm Friedrich Hegel (1770–1831)

    Love can no more continue without a constant motion than fire can; and when once you take hope and fear away, you take from it its very life and being.
    François, Duc De La Rochefoucauld (1613–1680)
