As the turbines are connected with generators, so the turbines must run with a constant speed so that the frequency of the electric current produced by the generators stay the same. To do that the discharge to the turbine needs to be altered suitably to keep the speed constant.

Statement I: The speed of a governed water turbine will remain constant irrespective of load.
Statement II: In governing, the water supply is regulated to maintain the speed constant.
Explanation:
The speed of a governed water turbine refers to the rotational speed of the turbine shaft. The governing system of a water turbine is responsible for regulating the speed of the turbine to maintain it constant, regardless of the load applied to the turbine. Let's analyze each statement individually and then determine their relationship.
Statement I: The speed of a governed water turbine will remain constant irrespective of load.
This statement is true. A governed water turbine is equipped with a governing system that adjusts the flow of water to the turbine in response to changes in load. The governing system ensures that the speed of the turbine remains constant, regardless of the load fluctuations. This is important to maintain the stability and efficiency of the turbine operation.
Statement II: In governing, the water supply is regulated to maintain the speed constant.
This statement is also true. Governing is the process of regulating the water supply to the turbine to maintain a constant speed. The governing system monitors the rotational speed of the turbine and adjusts the flow of water accordingly. If the speed tends to increase, the governing system reduces the water supply, and if the speed tends to decrease, the system increases the water supply. By regulating the water supply, the governing system ensures that the speed remains constant.
Relationship between the statements:
Both statements I and II are individually true, and statement II provides the correct explanation for statement I. The governing system is responsible for regulating the water supply to maintain a constant speed, which supports the assertion made in statement I.
In conclusion, the correct answer is option A: Both statement (I) and Statement (II) are individually true, and statement (II) is the correct explanation of Statement (I). The governing system in a water turbine ensures that the speed remains constant by regulating the water supply based on the load applied to the turbine.
