WebJan 30, 2024 · This is equivalent to a familiar definition of enthalpy: \[ \Delta H = H_{final} - H_{initial}\] As represented by the solution to the integral, enthalpy is a state function because it only depends on the initial and final conditions, and not on the path taken to establish these conditions. Therefore, the integral of state functions can be ... If a steady-state, steady-flow process is analysed using a control volume, everything outside the control volume is considered to be the surroundings. Such a process will be isenthalpic if there is no transfer of heat to or from the surroundings, no work done on or by the surroundings, and no change in the kinetic energy of the fluid. This is a sufficient but not necessary condition for isoenthalpy. The necessary condition for a process to be isoenthalpic is that the sum of each of …
