Exploring Exergy Concepts

When matter flows across the boundary of a control volume, an exergy transfer accompanying mass flow occurs, which is given by where e is the specific exergy (Eq. 7.2) and is the mass flow rate. An exergy transfer accompanying flow work, which is given by the result of Problem 7.8, also occurs at the boundary. Show that the sum of these exergy transfers is given by where e_f is the specific flow exergy (Eq. 7.14).
