What is meant by adiabatically?

What is meant by adiabatically?

Definition of adiabatic : occurring without loss or gain of heat adiabatic expansion of a gas.

What does cooling adiabatically mean?

Adiabatic cooling is the process of reducing heat through a change in air pressure caused by volume expansion. In data centers and other facilities, adiabatic processes have enabled free cooling methods, which use freely available natural phenomena to regulate temperature.

What is adiabatic and non adiabatic?

An adiabatic process is one with no loss or gain of heat to a volume of air. Conversely, if heat is supplied or withdrawn, the process is diabatic or nonadiabatic. Near the earth’s surface, where heat is exchanged between the earth and the air, the processes are diabatic.

What does adiabatic warming mean?

Adiabatic. Changes in temperature caused by the expansion (cooling) or compression (warming) of a body of air as it rises or descends in the atmosphere, with no exchange of heat with the surrounding air.

What is another word for adiabatic?

In this page you can discover 12 synonyms, antonyms, idiomatic expressions, and related words for adiabatic, like: non-isothermal, advective, oscillatory, inviscid, time-dependent, diabatic, isothermal, isochoric, isentropic, diffusive and isobaric.

What is the difference between adiabatic and evaporative cooling?

As already highlighted, evaporative cooling systems are a very energy efficient way of cooling air. Adiabatic coolers vary in energy use but most use between 50% and 100% more energy than evaporative coolers. They also typically take up as much as twice the space of a similar capacity evaporative cooling tower.

What is cooling with adiabatic dehumidification?

Adiabatic humidification (evaporative cooling): If moisture is evaporated into an air volume without any heat input or removal (this is the meaning of the term ‘adiabatic’), the latent heat of evaporation is taken from the atmosphere.

What is non adiabatic?

Definition of nonadiabatic : not occurring without loss or gain of heat : not adiabatic a nonadiabatic system.

What is adiabatic process example?

One of the good applications of the adiabatic process. The pendulum oscillating in a vertical plane is an example of it. A quantum harmonic oscillator is also an example of an adiabatic system. When we put the ice into the icebox, no heat goes out and no heat comes in.

Who coined the term adiabatic?

Etymology. 19th-century coinage (introduced by W. J. M. Rankine in the 1860s) based on Ancient Greek ἀδιάβατος (adiábatos, “impassable”), used of terrain (rivers, forests) by Xenophon, from ἀ- (a-, “not”) + διά (diá, “through”) + βατός (batós, “passable”), from βαίνω (baínō, “to go”).

What is adiabatic pressure?

Adiabatic compression of the air is defined as the compression in which no heat is added or subtracted from the air, and the internal energy of the air is increased, which is equal to the external work done on the air. The pressure of the air is more than the volume as the temperature increases during compression.

What is an example of adiabatic cooling?

Conversely, when a gas expands under adiabatic conditions, its pressure and temperature both decrease without the gain or loss of heat. A good example is the adiabatic cooling of air as it rises in the atmosphere to form clouds.

What is adiabatic evaporation?

Evaporative cooling, otherwise known as adiabatic cooling, works on the principle of water evaporation through which the air is cooled down to a comfortable temperature. It is a cooling and ventilation technique that uses water as its refrigerant.

What is an example of an adiabatic process?

An example of adiabatic heating is a heat engine piston that compresses a gas contained within a cylinder. Gas compression leads to a temperature rise. In many practical situations, the conduction of heat is assumed to be null.

What is non adiabatic electron transfer?

Diabatic (the term more often used is non-adiabatic) – electron transfer is a quantum jump from one curve to the other (curves cross). Adiabatic – (impassable to heat; involving neither loss nor acquisition of heat; – OED).

What is a real life example of adiabatic?

Which describes the adiabatic process?

Which best describes a characteristic of an adiabatic process? Heat is absorbed but not released by the system.
