Unit power is the power developed by a turbine when _______.a)Head on ...
The power developed by a turbine, working under a unit head is known as unit power of the turbine.
P = ρgQH ∝ QH
Q = AV ⇒ Q ∝ √H
P ∝ H√H ∝ H3/2
P = K2 H3/2
When H = 1; P = Pu
Pu = K2
P = Pu H3/2

Unit power is the power developed by a turbine when _______.a)Head on ...
Unit power is the power developed by a turbine when the head on the turbine is unity. Let's understand this concept in detail:

Head on Turbine:
- The head on a turbine refers to the energy available due to the difference in water level or pressure between the inlet and outlet of the turbine.
- It is usually measured in units of length, such as meters or feet.
- The head represents the potential energy of the water that can be converted into mechanical energy by the turbine.

Unit Power:
- Unit power is the power developed by a turbine when the head on the turbine is unity.
- Power is the rate at which work is done or energy is transferred.
- In the context of turbines, power is the rate at which mechanical energy is generated by the turbine.
- The unit power is a standardized measure that allows for easy comparison and analysis of turbine performance.

Explanation of the Correct Answer:
The correct answer to the given question is option 'C' - "Head on turbine is unity."
- This means that the head on the turbine is equal to 1 (unity).
- When the head on the turbine is unity, it implies that the potential energy available for conversion into mechanical energy is at a standard reference level.
- The unit power is determined based on this standard reference head value.
- It provides a baseline for comparing the power output of different turbines under identical head conditions.

Importance of Unit Power:
- Unit power is a fundamental concept in the field of hydraulic turbine engineering.
- It helps in the design, analysis, and performance evaluation of turbines.
- By using unit power, engineers can compare the efficiency and output of different turbines operating under similar head conditions.
- It facilitates the selection of suitable turbines for specific hydraulic power generation projects.

In conclusion, unit power is the power developed by a turbine when the head on the turbine is unity. It serves as a standardized measure for comparing the performance of turbines under identical head conditions.

Because of the population diversity, there is immense variety in Indian culture. The Indian culture is a blend of various cultures belonging to diverse religion, castes; regions follow their own tradition and culture.Indian Culture is one of the oldest cultures in the world. India had an urban civilization even during the Bronze age. The Indus Valley Civilization (Harappan Civilization) dates back to 3300 BC – 1300 BC.Distinct cultures different from each other co-exist together in a single country. Thus, in India, there is unity amidst vast cultural diversity. The way people live in India is reflected in their culture.Unity in Diversity: India is a land of unity in diversity where people of different sects, caste and religion live together. India is also called the land of unity in diversity as different groups of people co-operate with each other to live in a single society. Unity in diversity has also become the strength of India.Secularism: The word secularism means equality, impartiality, etc. towards all religion. India is a secular country, which means, equal treatment of all the religions present in India.Traditions: traditional cultural values GesturesTouching feet of elders: Indian tradition has rich cultural values. In India, younger show great respect to their elders. They touch the feet of their elders daily after waking up and especially on the festive occasions or before starting an important work.Namaste: The gesture of the Namaste greeting is also part of the Indian culture. People greet each other by saying "Namaste" while joining their hands. "Namaste" means "Hello". (Also read, the meaning of Namaste here.)Most Indians have a habit of shaking their heads while talking.Q. Why is India called a unity in diversity?
