Power of a governor is the

A mean force exerted at the sleeve for a given percentage change of speed
B workdone at the sleeve for maximum equilibrium speed
C mean force exerted at the sleeve for maximum equilibrium speed
D none of the mentioned

Correct Answer: none of the mentioned

The power of a governor is the work done at the sleeve for a given percentage change of speed. It is the product of the mean value of the effort and the distance through which the sleeve moves. Mathematically, Power = Mean effort × lift of sleeve
