WebPrior to this lesson, we have only considered steady-state processes. Now, we will learn how to apply the mass conservation equation to transient processes. A transient process is one in which one or more properties or process variables change with time. This makes the problem a lot more complicated. For starters, the 1st Law cannot be reduced ... WebMay 22, 2024 · A throttling process is a thermodynamic process, in which the enthalpy of the gas or medium remains constant (h = const). 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). highbrow technologies
