It is convenient to define the shape of the control volume so that all flow of matter, in or out, occurs perpendicular to its surface. One may consider a process in which the matter flowing into and out of the system is chemically homogeneous. Then th… Webenergy associated with flow work into/out of control volume is automatically taken care of. This is the main reason that enthalpy is defined!
