Two gaseous streams containing the same fluid enter a mixing

Two gaseous streams containing the same fluid enter a mixing chamber and leave as a single stream. For the first gas the entrance conditions areA1 = 500 cm2, v1 = 130 m/s, p ₁ = 1.60 kg/m ³  . Forthe second gas the entrance conditions areA2 = 400 cm ² , m ² = 8.84 kgjs, v ₃ = 0.502 m ² /kg. The exit stream condition is v ₃ = 130 mjs and v ₃ = 0.437 m ³  fkg. Determine (a) the total mass flow leaving the chamber; (b) the velocity of gas 2.
