A. 2725 B. 1090 C. 545 D. 110 E. NOTAA generator driven by a wind turbine is required to deliver 5 MW of power at the generator terminals. The turbine is a two-blade propeller rotating about a horizontal axis and the maximum permitted shear stress of the turbine shaft is 55x106 N/m2 The rotor is designed to operate at a rotational speed of 45 revolution per seconds .The stage efficiencies are Cp 0.32, ngb = 0.90, ng = 0.92. %3D . (i) If the turbine delivers its rated power at a wind average speed of 22 m/s, calculate the corresponding diameter of the propeller and its TSR, assuming a typical value for the overall efficiency. The air density may be assumed to have a value 1.29 kg/m³. (ii) Calculate the torque on the turbine shaft.The connection between an electric motor and a construction machine shaft is provided by means of a rigid coupling with flanges, through which the moment is transferred via the coupling flanges.The power of the electric motor is 35kw and the speed is 870rpm. The coupling flanges are connected with three bolts of quality 5.6 with a placement diameter of 40 mm.The surface pressure safety stress for bolts is 16 MPa. The contact length of the bolt with the coupling flange is 12 mm. The coefficient of friction on the flange surfaces is 0.14; the operating factor for the coupling is 0.8.
