Question: sample air 1 2 and carbon dioxide 394 5 flow...

Question details

Sample: Air (1- 2) and carbon dioxide (3-94- 5) flow through a system as shown. For the air, assume ideal gas behavior with variable specific heats. For the carbon dioxide, assume ideal gas behavior with constant specific heats evaluated at 650 K. Find L: Air 1800 K 2: 400 K 0.1 kg/s1.0 MPa )20 kJ/kg Nozzle 3: CO2 0.8 MPaExchanger Heat 660 K 0.4 kg/s 100 kPa 400 m/s (14 pts) The carbon dioxides temperature as it enters the heat0 m/s exchanger, Ts (K) (6 pts) The volumetric flow rate at the nozzles inlet, , (m/s).
