Question

Consider the following characteristics:
1. High steam and blade velocities.
2. Low steam and blade velocities
3. Low speeds of rotations.
4. High carry-over loss.
Which of these characteristics are possessed by a simple impulse turbine?

• A. 1 and 4
• B. 3 and 4
• C. 2 and 3
• D. 1 and 2

Answer 1

The correct option is A 1 and 4

• In impulse turbine, all the available energy is converted into kinetic energy by a nozzle, hence it has high steam and blade velocities.
• Speed of rotations are also high, thats why compounding is done.
