6.20 A 0.4-m-diameter tube axial fan has a performance target of 0.8m³ /s and a static pressure rise of 225 Pa with p = 1.0 kg/m3. Determine a good hub size and a reasonable speed for the fan. Develop velocity vector diagrams for the inlet and outlet stations at 2r/D = 0.75 (the 75% blade radial station). Estimate static and total efficiencies and modify the outlet vector diagram to account for total pressure losses in the blade row (based on n.r from Cordier estimates). 6.22 A vane axial fan has Q - 12m³/s N - 1050rpm p - 1.18kg/m³ , D = 1.0m, and d = 0.7 m. Determine the maximum attainable total pressure rise for the fan if the value of W2 = C2/C1 at the vane W1 hub station must be at least 0.62. Assume initially that 1.7 = 0.75.
