Fractional Change of Speed:
The fractional change of speed refers to the change in speed of the governor due to certain conditions or factors. It is usually expressed as a percentage of the original speed.
Displacement of the Sleeve:
The displacement of the sleeve in a governor refers to the movement of the sleeve in response to changes in the speed of the governor. It is the distance by which the sleeve moves up or down.
Interpretation of High Displacement:
When the displacement of the sleeve is high, it means that the sleeve is moving a significant distance in response to the changes in speed. This indicates that the governor is responding strongly to the changes and is highly sensitive to the variations in speed.
Explanation of the Correct Answer:
The correct answer for the given question is option 'C' - Sensitive. This means that when the displacement of the sleeve is high, the governor is said to be sensitive.
Reasoning:
When the displacement of the sleeve is high, it indicates that the governor is responding strongly to the changes in speed. This sensitivity is desirable in a governor as it allows it to quickly adjust the fuel supply or input to the engine or machine in order to maintain a constant speed.
A sensitive governor is able to effectively control the speed of the engine or machine and ensure that it operates at the desired speed regardless of the load or external conditions. It is able to quickly respond to changes and make necessary adjustments to maintain the stability and performance of the system.
On the other hand, if the displacement of the sleeve is low, it indicates that the governor is not responding strongly to the changes in speed. This lack of sensitivity can lead to instability in the system and result in hunting, where the governor oscillates around the desired speed rather than maintaining a steady state.
Therefore, when the displacement of the sleeve is high, the governor is said to be sensitive, indicating its ability to effectively control the speed and maintain stability in the system.
