Question

Two gaseous streams streams enter a mixing chamber through two sections and leaves through one section. At entrance; A1 = 450 cm2 , V1 = 150 m / sec , v1 = 0.625 m3 / kg , and A2 = 380 cm2 , V2 = 55 m / sec, ρ2 = 2 kg / m3 . At exit; V3 = 245 m / sec , and v3 = 0.58 m3 / kg. Draw the figure and determine; (a) the mass flow (kg / sec ) at section 2, and (b) the area of the exit section (cm2).
