A turbine-driven 21-megawatt shipboard propulsion generator (alternator) produces 4160-volts, 3-phase, 60-Hz power. The rotor rotates at 3600 rpm, and the shaft torque delivered from the turbine to the alternator is 42,337 ft-lb.
Determine a) the number of poles in the alternator, and
b) the efficiency of the alternator.
