🔍 Key Concepts

• Main condenser function in a steam cycle (creating vacuum, condensing exhaust steam, recovering condensate) • Effect of non‑condensable gases (air) on condenser vacuum and heat transfer • Relationship between condenser pressure and turbine exhaust steam enthalpy

💭 Think About

• Think about what happens to the condenser pressure and vacuum when air leaks in. How does that change the turbine’s exhaust conditions? • Which option describes a thermodynamic change that would make the turbine do less work per pound of steam? • Consider which choices are simple statements of flow/mixing, and which relate directly to energy (enthalpy) at the turbine exhaust.

✅ Before You Answer

• Identify how air (a non‑condensable gas) affects heat transfer and pressure in the condenser • Recall what happens to steam enthalpy when condenser pressure rises (saturation temperature and enthalpy at exhaust change) • Eliminate any choices that do NOT clearly tie back to a change in turbine work output or overall cycle efficiency
