🔍 Key Concepts

• Rankine cycle efficiency and how condenser pressure affects it • Relationship between exhaust (back) pressure and turbine work output • What physical problems (creep, turbulence, condensate depression) actually relate to pressure vs. temperature or flow patterns

💭 Think About

• Ask yourself: In a steam plant, why do we want the condenser to operate under vacuum rather than at or above atmospheric pressure? • Which of the listed effects would directly increase the amount of useful work that can be extracted from the expanding steam in the turbine? • Which choices describe issues (like creep or turbulence) that are more about material temperature limits or flow design rather than simply the pressure level in the exhaust trunk?

✅ Before You Answer

• Identify which option clearly connects lower exhaust (back) pressure to more expansion of steam and greater energy conversion to work • Eliminate any options that confuse pressure effects with material thermal stress (creep) or flow pattern issues that are mainly design-related, not vacuum-related • Confirm that your chosen option matches how lowering condenser pressure affects the overall thermal efficiency of the steam cycle
