Which part of a steam turbine is the central rotating component?

• Nozzles

• Casing

• Rotor

• Bearings

What is the function of the blades in a steam turbine?

• Supporting the rotor

• Reducing friction

• Converting steam energy into rotational energy

• Connecting the rotor to machinery

What houses the rotor and blades in a steam turbine?

• Casing

• Nozzles

• Shaft

• Bearings

Which component directs high-pressure steam onto the blades with high velocity?

• Rotor

• Nozzles

• Bearings

• Shaft

What is the role of the shaft in a steam turbine?

• To house the rotor and blades

• To convert steam energy into rotational energy

• To reduce friction

• To connect the rotor to the generator or other machinery

How does a steam turbine convert thermal energy into mechanical work?

• By reducing friction

• By using electric motors

• By expanding high-pressure steam through nozzles

• By cooling down steam

What is an impulse turbine characterized by?

• High rotational speed and simple construction

• Lower rotational speed and complex construction

• Using both pressure and reaction force

• Operating at low flow rates

Which type of steam turbine uses both pressure and reaction force for energy extraction?

• Impulse turbine

• Axial flow turbine

• Reaction turbine

• Radial flow turbine

In an impulse turbine, how does steam interact with the blades?

• Steam expands partially in the blades

• Steam expands completely in the nozzles before striking the blades

• Steam changes its pressure but not its velocity

• Steam creates a reaction force in the blades
