WebJul 21, 2024 · The thermodynamic process inside the open system is therefore completely irrelevant for the determination of the flow work. Thus, the flow work is not a process quantity, as one might mistakenly think on the basis of the term work, but a state variable! Note: Sometimes, only the individual products of pressure and volume are referred to as … WebThermodynamic. equilibrium. A particularly important concept is thermodynamic equilibrium, in which there is no tendency for the state of a system to change spontaneously. For example, the gas in a cylinder with a movable piston will be at equilibrium if the temperature and pressure inside are uniform and if the restraining force on the piston ...

In fact, the throttling process is one of isenthalpic processes. During the throttling process no work is done by or on the system (dW = 0), and usually there is no heat tranfer ( adiabatic) from or into the system (dQ = 0).
