100. Suppose a prime mover rotates at a steady speed of 900 rpm at rated full load and rotates at a steady speed of 1000 rpm at no load. Assuming that no adjustments have been made to the governor speed control setting, what is the speed regulation of the prime mover expressed in percent?
Speed regulation is calculated as the change in speed between no-load and full-load conditions, divided by the full-load speed, then multiplied by 100%, resulting in 11.1%.
