Question 1 of 27070

Which of the following statements represents an example of a throttling loss in a turbine?

🔍 Key Concepts

• Throttling process in thermodynamics (pressure drop with no work done and ideally no change in enthalpy) • Where useful work is extracted in a turbine versus where energy is lost without producing work • Difference between friction losses and throttling losses in steam flow

💭 Think About

• In which choice does steam experience a pressure drop without doing useful work on the turbine blades? • Which options describe normal turbine operation (where steam is intended to expand and do work) and which describe an unintentional pressure drop? • Think about where a control or restriction in the flow path causes a loss, rather than the designed expansion through nozzles or blades.

✅ Before You Answer

• Identify which component acts like a restriction or valve causing a throttling effect rather than a working stage of the turbine. • Check which choices describe designed expansion (where work is done) versus a parasitic loss where no useful work is produced. • Verify which option best matches the thermodynamic idea: pressure drop with little or no change in enthalpy (throttling), not friction heating or leakage.
