Answer:
Considering friction, the frictional resistance is assumed to be equivalent to a force R acting on the sleeve.
Explanation:
Porter governors are illustrated with dead weight loaded centrally. Therefore, it would be seen that the dead weight causes the h for a given % change in speed to grow in the ratio (W+w)/w. Friction has the effect of increasing the governor's speed range, governor effort, and governor power. The governor speed of a porter governor increases when the sleeve moves higher and reduces when the sleeve moves downward. When the sleeve rises, the supply of the working fluid diminishes; when it descends, the supply increases. Engine speed and governor speed both decrease as engine load rises. As a result, the centrifugal force acting on the balls is reduced.
Thus, friction has the effect of increasing the governor's speed and power and the frictional resistance is assumed to be equivalent to a force R acting on the sleeve.
