Q

Approximately how far could a straight stream of water reach if the fire hose pressure is reduced to 60 PSI?

🔍 Key Concepts

• Relationship between hose pressure (PSI) and stream reach distance • Typical reach of a straight fire stream at standard pressures (e.g., around 100 PSI) • How reducing pressure usually affects the effective range of a water stream

💭 Think About

• First, recall or estimate the approximate reach of a straight stream at common firefighting pressures (like 100 PSI). Is it closer to 50, 100, 150, or 200 feet? • Then consider: when pressure is reduced to 60 PSI, will the stream reach more, less, or about the same distance as at higher pressure? • Compare the answer choices and eliminate those that seem unrealistically long or short for shipboard hose streams at only 60 PSI.

✅ Before You Answer

• Verify what a typical straight stream reach is at about 100 PSI on a standard fire hose/nozzle used on vessels. • Think about how much the distance would drop when pressure goes from around 100 PSI down to 60 PSI—it shouldn’t increase. • Check which choice best represents a moderate but reduced reach, not an extreme maximum distance.
