🔍 Key Concepts

• condensation process in a surface condenser and what happens if steam is not fully condensed • relationship between condensate flow rate, temperature, and the ability to absorb latent heat from steam • how changes in pump speed or makeup feed would practically affect condenser vacuum and venting

💭 Think About

• Which condition would make it harder for the condenser to remove the latent heat of vaporization from the steam, so that some steam leaves as visible vapor at the vent? • Think about whether ‘more water’ or ‘colder water’ in the condenser would increase or decrease the chance of visible vapor at the vent. • For each option, ask: does this make condensation more complete, or less complete?

✅ Before You Answer

• Verify which option would reduce effective heat transfer in the condenser, leading to steam not fully condensing. • Check which options would improve condenser performance and thus are unlikely to cause vapor at the vent. • Consider normal troubleshooting practice: when you see vapor at an air ejector vent, what primary condition in the condenser are you most suspicious of?
