🔍 Key Concepts

• water hammer in steam lines and how it forms • role of condensate (water) in steam piping when systems are started up • effect of how you open valves versus how you prepare the line before use

💭 Think About

• Which option directly removes or minimizes the amount of liquid water that can be slammed by fast‑moving steam in the line? • One choice describes something you should do before operating any steam‑driven machinery. How would that affect water hammer? • Look at each option and ask: does this deal with trapped water, flow rate changes, or just heat loss? Which one truly tackles the cause of water hammer?

✅ Before You Answer

• Identify which choice deals specifically with removing accumulated condensate from the line. • Check which options are about procedure before start‑up versus normal operation or insulation. • Eliminate any choice that does not clearly reduce or remove liquid water in the steam piping.
