. Two steady flows of air enter a control volume, as shown in Fig. One is a 0.035 kg/s flow at 350kPa, 160°C, state 1, and the other enters at 450 kPa, 25°C, state 2. A single flow exits at 100 kPa, -30°C, state 3. The control volume rejects 2.5 kW heat to the surroundings and produces 4.5 kW of power output. Neglect kinetic energies, determine the mass flow rate in kg/s at state 2.
