Governor Effort and Power:

Governor effort and power may be utilized to compare the effectiveness of different kind of governors.

Governor Effort

This is defined like the mean force exerted on the sleeve throughout a given modified in speed.

While governor speed is constant the total force at the sleeve is zero. While governor speed enhance, there shall be a total force on the sleeve to move it upwards and sleeve begin moving to the new equilibrium location where total force becomes zero.

Governor Power

This is defined as the work done at the sleeve for a given modification in speed. Thus, Power of governor = Governor Effort × Displacement of sleeve
