Q

The cylinders and intercoolers of most low-pressure air compressors are cooled by __________.

If the question has a related picture, it will appear here.

🔍 Key Concepts

• heat transfer in compressors (how cylinders and intercoolers get rid of heat) • difference between lubricants and cooling mediums • common shipboard cooling systems for low‑pressure air compressors

💭 Think About

• When air is compressed, what happens to its temperature, and how must that heat be removed in continuous duty shipboard service? • Which of the listed substances is most practical and commonly used to carry heat away from machinery on ships? • Think about what is normally used to cool engines, auxiliary machinery, and heat exchangers in an engine room.

✅ Before You Answer

• Eliminate any options that are mainly used as lubricants rather than primary coolants for compressor cylinders. • Consider which medium can be easily circulated through jackets and intercoolers on a ship. • Ask whether any option is typically reserved for firefighting or special systems, not routine machinery cooling.
