WebJun 27, 2024 · An isentropic process is by definition a process that is both adiabatic and reversible. So you can't have an isentropic process that is not adiabatic. However, you can have an adiabatic process that is not isentropic, if it is not a reversible process. An example is an adiabatic process involving friction losses. forest river wildcat 5th wheel rv https://makendatec.com

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).
