Open system entropy balance
Did you know?
WebAn entropy balance is applied to the entire system consisting of the valve, heat exchanger, and two flow streams with the assumption of SSSF ( d S / d t = 0 ). Also, the overall system is adiabatic ( Q ˙ = 0) since the heat transfer between the air and refrigerant is internal to the system.The simplified entropy balance becomes Web15 de jan. de 2004 · It is easy to understand from the viewpoint of the thermodynamic theory of open-system that only strong negative entropy flow from the outside can balance the spontaneous entropy growth within the system and enable the system to reach a …
