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.
