Question

8. The pulley of an old generator set has a diameter of 20 inches. The belt exerts a pull of 353 lbs on the pulley, and the generator set runs at 900 rpm. What is the approximate kW rating of the generator set? 9. A DC generator has a no-load output voltage rating of 120 V. The armature circuit resistance is 0.95 ohms, and its field coils are separately energized. If a load rated 2.2 kW at 115 V is connected across the terminals, neglecting the effect of armature reaction and line drop, what power would be absorbed by the load? 10. Two shunt generators A and B operate in parallel, and their load characteristic may be taken as a straight line. The voltage of generator A falls from 240 volts at no load to 220 volts at 200 amperes, while that of generator B falls from 245 volts at no load to 220 volts at 150 amperes. Determine the terminal voltage when the load is 67 kW.
