where q is heat added to the process, T is temperature of the process, and sirr is the entropy of the irreversible process.5 For adiabatic flows, where no heat enters or leaves (dq/T = 0), the change in entropy simply describes the losses generated in the compression process. These lo...

The real isentropic exponent varies (κr) as a function of flowing pressure and temperature (Pf, Tf) for a given composition. An appropriate equation of state is required to calculate the real isentropic exponent. View chapterExplore book Physical Properties and Process Conditions James E. ...
What is the final temperature, in oC, of the steam? Isentropic process The process in which the state of a substance changes but without any change in its entropy is know as Isentropic process . To solve this problem we will have...
the change in entropy between the inlet and outlet states can be interpreted as the entropy generation per mass flow: • For a steady, reversible, adiabatic process, it is also isentropic: steady state adiabatic gen out out in in in in S s m s m T Q dt dS m (due to mass conserva...
), the WF turns into the vapour and is expanded to produce useful work in the turbine (1-2 process) till the condensation pressure, the after-condensed WF (point 2) is driven to the condenser (point 2′) to reject the heat till the condensation temperature (2-2′-3′-3 process). ...
and the zones having severe temperature drop were those with the value being larger than 0.8 PVU.This study indicated that the 315 K isentropic potential vorticity can be used as an effective tool for analyzing and predicting the sudden cold wave and extreme snowstorm process in spring,and also...
In spring ice, at least 6 processes can affect CO2 dynamics, namely: (1) temperature change and (2) related melting of ice crystal, (3) biological activity, (4) dissolution of carbonate minerals, (5) internal convection and (6) air-ice gases exchanges. Each process can significantly ...
