Use the devices below with the given operating conditions. The mass flow rate of the air is \( 2 \mathrm{~kg} / \mathrm{s} \). The mass flow rate of the refrigerant is \( 1 \mathrm{~kg} / \mathrm{s} \). If necessary, evaluate specific heats at \( 300 \mathrm{~K} \). - Determine the temperature of the refrigerant exiting the heat exchanger in Celsius. \[ \begin{array}{l} T_{1}=300 \mathrm{~K} \\ T_{3}=293 \mathrm{~K} \\ P_{4}=7 \mathrm{bar} \\ T_{4}=26.72^{\circ} \mathrm{C} \\ X_{4}=0 \end{array} \] \( P_{5}=2 \) bar
