🔍 Key Concepts

• Relationship between condenser vacuum and the saturation temperature of steam at that vacuum • Meaning of condensate depression in a main condenser • Purpose of maintaining some temperature difference between condensate and saturation temperature

💭 Think About

• Which term describes how many degrees below the saturation temperature (for the existing vacuum) the actual condensate is? • Look at each choice and ask: is this a commonly used thermodynamic term for describing temperature difference in a condenser, or something else? • Think about why engineers care about the temperature of the water leaving the condenser compared to the saturation temperature—what efficiency or protection issue does it relate to?

✅ Before You Answer

• Identify which option directly refers to condensate temperature relative to saturation temperature at the current vacuum • Eliminate any options that are not standard condenser performance terms used in steam plant thermodynamics • Verify which term is associated with avoiding re-evaporation (flashing) of condensate in the hotwell or condensate system
