Two steady flows of air enter a control volume, as shown in Fig. P4.89. One is a 0.025 kg/s flow at 350 kPa, 150◦C, state 1, and the other enters at 450 kPa, 15◦C, state 2.Asingle flow exits at 100 kPa,−40◦C, state 3. The control volume ejects 1 kW heat to the surroundings and produces 4 kW of power output. Neglect kinetic energies and determine the mass flow rate at state 2.
