The thermodynamic systems shown below operate at steady state. For the specified control
volume, write the energy balance and mass balance, assuming negligible kinetic and
potential energy effects. The equations must reflect the state points shown in the
accompanying diagram. No partial points will be given to wrong answers, and answers with
notations/subscripts that are not consistent with the state points in the accompanying diagram.
