$3\mathrm{.}1)$ A fixed control volume $($CV$)$ has three one$-$dimensional boundary sections, as shown in the below figure and the corresponding table with properties at each state. The flow within the control volume is steady. Write the differential continuity equation for this system and find the rate of change of energy of the system that occupies the control volume at this instant with the given information.
