🔍 Key Concepts

• High velocity fog nozzle characteristics and purpose • Relationship between water pressure and droplet size / spray reach • Typical minimum operating pressure for effective fire-fighting fog streams on marine systems

💭 Think About

• Think about why a fog nozzle needs a certain minimum pressure: what happens to the spray pattern and droplet formation at lower pressures? • Consider standard fire main pressures on ships: which option best matches a realistic minimum to create a strong, cone-shaped fog pattern? • Which pressures listed are more typical for full-capacity fire main operation versus barely adequate spray?

✅ Before You Answer

• Compare each choice to typical ship’s fire main pressure ranges you’ve studied. • Ask: at which minimum pressure would a nozzle reliably break water into fine droplets for maximum heat absorption and steam production? • Eliminate any options that seem too low to maintain a solid, well-formed fog pattern from a high velocity nozzle.
