WitrynaBecause the process is both reversible and adiabatic, it is isentropic. Therefore : S 2: 6.8210: kJ/kg-K: At this point we know values of two intensive variable for state 2, so we can use the NIST Webbook to determine the value of any other property. In this case, we need H 2. First, we need to determine the phases that exist at state 2. WitrynaAnswer (1 of 10): Good question. For the case of simplicity, let us take a control mass/closed system, though the discussion is equally relevant to a control volume. Now for any control mass, there are two ways in which its entropy can change, through heat transfer atthe boundary and through entr...

WitrynaA reversible, adiabatic process is always isentropic since no entropy generation due to irreversibilities (sgen=0) and no change of entropy due to heat transfer (ds=?Q/T=0). The reverse is not always true: An isentropic process is not necessary a reversible, adiabatic process. WitrynaIs isentropic adiabatic? In thermodynamics, an isentropic process is an idealized thermodynamic process that is both adiabatic and reversible . The work transfers of the system are frictionless, and there is no net transfer of heat or matter. Witryna1 sie 2024 · Solution 2. Taken from wikipedia: In thermodynamics, an isentropic process is an idealized thermodynamic process that is adiabatic and in which the work transfers of the system are frictionless; there is no transfer of matter and the process is reversible.
