Q1. What is the steam turbine's work?
Ans. 
Steam turbine converts thermal energy in steam into mechanical energy.
• Steam enters the turbine and expands, causing the rotor to spin

• The spinning rotor is connected to a generator, producing electricity

• Used in power plants, refineries, and other industrial applications

Q2. What is the impulse turbine efficiency?
Ans. 
Impulse turbine efficiency is the ratio of actual work output to the theoretical work input, typically ranging from 70-90%.
• Impulse turbine efficiency is calculated as the ratio of actual work output to the theoretical work input.

• It is typically in the range of 70-90%, depending on the design and operating conditions of the turbine.

• Factors affecting impulse turbine efficiency include blade design, nozzle efficiency, and...read more

Q3. What is the obsolete angle of impulse turbine?
Ans. 
The obsolete angle of impulse turbine is the angle at which the blades are set in relation to the direction of the water flow.
• Obsolete angle is typically around 20-22 degrees for impulse turbines.

• It determines the efficiency and performance of the turbine.

• Incorrect angle can lead to reduced power output and efficiency.

• Examples: Pelton wheel, Turgo turbine.

Q4. What is the blade efficiency of impulse turbine?
Ans. 
Blade efficiency of impulse turbine is typically around 80-90%.
• Blade efficiency is a measure of how effectively the blades of a turbine convert the kinetic energy of the fluid into mechanical energy.

• It is calculated as the ratio of the actual work done by the blades to the work that would be done if the fluid were to expand isentropically.

• Blade efficiency for impulse turbines is generally higher than reaction turbines,...read more

Q5. What is the efficiency of impulse turbine?
Ans. 
The efficiency of an impulse turbine is typically around 70-90%.
• Efficiency is calculated as the ratio of actual work output to the theoretical work input.

• Impulse turbines have high efficiency due to the fact that the energy transfer occurs in stages.

• Efficiency can be affected by factors such as blade design, operating conditions, and maintenance.

• Examples of impulse turbines include Pelton wheel and Turgo turbine.
