An ideal wind-turbine, 12 m in diameter, operates at a theoretical efficiency (9th) (equation given below) of 50% in uj = 14 m/s wind. If the air density is 1.2 kg/m² and (u + ua)(u? – uz) 2u 2 3 nin U2 = u3 = (uj + u4)/2 2 P1 = P4 = Patm Determine, a) The axial force on the windmill. (assume uniform flow at positions) b) The mean (gage) pressures immediately in front of (P2-Patm) and behind (P3-Patm)...
