🔍 Key Concepts

• Water hammer in steam lines and what causes it • Role of condensate (water) inside steam pipes • Why proper drainage and insulation matter in steam systems

💭 Think About

• Which choice reduces or removes the presence of liquid water in a high‑velocity steam line? • How does insulation affect the formation of condensate and puddling in low points of the line? • What valve‑operating practice would make water hammer worse rather than better?

✅ Before You Answer

• Identify which options deal directly with condensate control (draining, preventing pooling). • Consider which option might actually increase pressure surges instead of preventing them. • Check which option aligns with standard engine room practice for maintaining steam piping (think drains, traps, and insulation).
