The ducted fan unit shown in the figure has mass m = 100 kg and is supported in the vertical position on its flange at A. The unit draws in air with a density p = 1.200 kg/m³ and a velocity V₁ = 5 m/s through an inlet with diameter D₁ = 1.00 m. It discharges air through two outlets at the bottom of the fan. The mass flow rate through each outlet is 1/2 of the entering mass flow rate, and the velocity at each outlet is V₂ V3 = 15 m/s. Both inlet and outlet pressures are atmospheric.
