A Synchronous Turbo Generator is otating at 1800rpm, has acylindrical rotor(the rotor is the rotating component of the Turbogenerator) 3meters long, 1m in diameter, whose mass has a volumedensity of 7800 Kg/m3 .
a) What is the kinetic energy possessed by the spinning rotor?
b) Determine the required torque to bring the Turbo Generatorfrom rest to its rated speed of 1800rpm in 2 hrs.
