Isenthalpic process An isenthalpic process or isoenthalpic process is a process that proceeds without any change in enthalpy, H; or specific enthalpy, h.

When examining thermodynamic processes some simplifying assumptions may be applied to help describe and analyse a given system.

These simplifications can be viewed as ‘ideal’ thermodynamic processes and include adiabatic, isenthalpic, isentropic, isobaric, isochoric, isothermal, isentropic, polytropic and reversible processes. This article provides a brief overview of each process type and suitability to a given thermodynamic system. Each type of thermodynamic process presented in this article has the simplifying characteristic that one or more property is held peocess while the process takes place.

Isenthalpic process – Unionpedia, the concept map

The table below summarises the constant properties for each type of thermodynamic process. In practice this assumption is most often used for rapidly acting systems i.

Essentially and isenthalpic system is an adiabatic system that is irreversible and extracts no work. The isenthalpic assumption is typically applied to determine the maximum temperature change in a system with changes in pressure. Since no energy is dissipated as heat an isentropic process is both adiabatic and reversible.

Throttling Process – Isenthalpic Process

Steady state fluid systems are often best represented as adiabatic, but to give an estimation of the efficiency of the process the isentropic performance of iesnthalpic system is often related to the adiabatic or actual performance. This is referred to as the adiabatic or isentropic efficiency:. Assuming that the quantity of gas in an isobaric process remains constant the work done by the system is directly promotional to the change in volume or temperature of the system.

Isochoric processes can also be referred to as isometric or isovolumetric. There may be energy flow into and out of the system, however only the amount required to keep the temperature of the system constant. An isotropic system is not strictly a thermodynamics system, however pdocess may easily be confused for one from the name.

Isenthalpic process

Isotropic systems are uniform regardless of direction. A polytropic fluid system follows the relationship: A reversible process is one which is performed as if it were always at equilibrium, and without the production on entropy.

This system is purely hypothetical since entropy is increased iisenthalpic any process occurring in a finite time. A reversible process is always at equilibrium as the process progresses and thus represents the maximum efficiency that is possible in the conversion between work and energy for the system. Summary When examining thermodynamic processes some simplifying assumptions may be applied to help describe and analyse a given system.
