An adiabatic process (adiabatic from Ancient Greek ἀδιάβατος (adiábatos) ' impassable ') is a type of thermodynamic process that occurs without transferring heat between the thermodynamic system and its environment. Unlike an isothermal process, an adiabatic process transfers energy to the surroundings only as work and/or mass flow.
In the study of combustion, the adiabatic flame temperature is the temperature reached by a flame under ideal conditions. It is an upper bound of the temperature that is reached in actual processes. There are two types of adiabatic flame temperature: constant volume and constant pressure, depending on how the
Adiabatic circuits are low-power electronic circuits which use "reversible logic" to conserve energy. [1] The term " adiabatic " refers to an ideal thermodynamic process in which no heat or mass is exchanged with the surrounding environment, alluding to the ability of the circuits to reduce energy loss as heat.
In thermal physics and thermodynamics, the heat capacity ratio, also known as the adiabatic index, the ratio of specific heats, or Laplace's coefficient, is the ratio of the heat capacity at constant pressure (C P) to heat capacity at constant volume (C V).
The saturated adiabatic lapse rate (SALR), or moist adiabatic lapse rate (MALR), is the decrease in temperature of a parcel of water-saturated air that rises in the atmosphere. It varies with the temperature and pressure of the parcel and is often in the range 3.6 to 9.2 °C/km (2 to 5 °F/1000 ft ), as obtained from the International Civil ...
Adiabatic process: occurs without loss or gain of energy by heat; Isenthalpic process: occurs at a constant enthalpy; Isentropic process: a reversible adiabatic process, occurs at a constant entropy; Isobaric process: occurs at constant pressure; Isochoric process: occurs at constant volume (also called isometric/isovolumetric)
It's flu season right now, and the U.S. is in the midst of a wave that's straining hospitals.But not all influenza is the same. There are some notable differences between flu A and flu B strains.
Adiabatic (from Gr. ἀ negative + διάβασις passage; transference) refers to any process that occurs without heat transfer. This concept is used in many areas of physics and engineering. This concept is used in many areas of physics and engineering.
