Estimate static and total efficiencies and modify the outlet vector diagram to account for total pressure losses in the blade row (based on ɳ𝑇 from Cordier estimates).
6.22 A vane axial fan has 𝑄 = 12𝑚³/𝑠 , 𝑁 = 1050𝑟𝑟𝑟 , 𝜌 = 1.18𝑘𝑘/𝑚³ , D = 1.0 m, and d = 0.7 m
Determine the maximum attainable total pressure rise for the fan if the value of
------ = C1/ C2
at the vane hub station must be at least 0.62. Assume initially that ɳ𝑇 = 0.75.
