Which of the following statement(s) is/are incorrect? (i) A turbine is called an impulse turbine if at the inlet of the turbine total energy is only kinetic energy (ii) A turbine is called a reaction turbine if at the inlet of the turbine the total energy is kinetic energy and pressure energy (iii) The inward flow reaction turbine having radial discharge at the outlet is known as Kaplan turbine
The Fourneyron turbine is _________ reaction turbine.
Consider the following statements in connection with hydraulic turbines: 1. The Kaplan turbine is a radial flow turbine in which the guide vane angles as well as the runner vane angles are adjustable. 2. Francis and Kaplan turbines are provided with draft tubes which carry water from exit of runner to tail water to increase the gross head across the turbine. 3. The parts of turbines susceptible to cavitation are the guide vanes and runner vanes – drastically reducing the turbine efficiency. 4. The specific speed of a 4-jet Pelton turbine will be 28 if the specific speed of a single-jet Pelton turbine is 14. Which of the above statements are correct?

For each question, mark out an appropriate answer choice that you think is correct. Statements: Some kind are intelligent. Some cruel are kind. All cruel are people. No people is an animal. Conclusions: I. No cruel is an animal. II. Some kind are not an animal. III. Some kind are not intelligent. IV. All animals are intelligent.
Consider the following statements regarding a turbine: 1. Specific speed plays an important role in the selection of the type of turbine. 2. An increase in specific speed of the turbine is accompanied by higher maximum efficiency. 3. The runner of too high specific speed with high available head increases the cost of the turbine on account of the high mechanical strength required. Which of the above statements are correct?
