Types of multi-stage steam turbines Identify which turbine configurations can be multi-stage in practical steam turbine design. Choose the correct option.

Difficulty: Easy

Velocity compounded type
Reaction type
Pressure compounded type
All of these

Correct Answer: All of these

Explanation:

Concept
Multi-staging can be implemented via:

Velocity compounding (Curtis): several rows of moving blades to extract jet velocity.
Pressure compounding (Rateau): multiple nozzles with pressure drops split over stages.
Reaction (Parsons): pressure drop shared between fixed and moving blades over many stages.

Final Answer
All of these

Definition of axial discharge from turbine blades A turbine has axial discharge when the absolute exit steam direction makes what angle with the blade motion (tangential) direction? Choose the correct option.
Terminology: axial-flow turbines Statement: A turbine in which the general direction of steam flow is parallel to the turbine axis is called an axial-flow turbine. Decide whether the statement is correct.
Critical (throat) pressure in a De Laval nozzle: superheated steam 10 bar → 0.1 bar Given: Superheated steam expands from 10 bar to 0.1 bar in a De Laval nozzle. Find: Pressure at the minimum area (throat) at choked condition using the standard critical ratio for superheated steam. Choose the correct option.
Effect of turbine blades on steam direction Statement: The turbine blades do not change the direction of steam issuing from the nozzle. Decide whether the statement is correct.
Steam turbines — definition of efficiency ratio The ratio of the total useful heat drop (actual work obtained from the fluid) to the total isentropic heat drop across the turbine/stage. Choose the correct name of this efficiency.
Steam nozzle losses — where friction is assumed to act In a practical analysis of a convergent–divergent steam nozzle, the entire frictional loss is assumed to occur in a specific region of the nozzle. Identify that region.
