Question 1 of 27070

According to Coast Guard Regulations (46 CFR), on a freight vessel, each fire pump must be capable of supplying the two highest outlets simultaneously, at a Pitot tube pressure of __________.

🔍 Key Concepts

• 46 CFR requirements for fire pumps on freight vessels • Meaning of Pitot tube pressure in relation to fire main systems • Minimum pressure needed to effectively supply two highest fire hose outlets simultaneously

💭 Think About

• First, think about what pressure is typically needed at a fire hose nozzle to be effective on a large seagoing vessel. Is it closer to low, medium, or high domestic water pressure? • Consider why the regulation specifies the two highest outlets. How does height affect the pressure a pump must deliver? • Ask yourself which option seems more consistent with a system designed for shipboard firefighting, not just simple washdown.

✅ Before You Answer

• Look up 46 CFR fire protection requirements for freight vessels – fire main systems (Subchapter I – Cargo and Miscellaneous Vessels). • Verify the specific CFR language about each fire pump being able to supply two highest hydrants/outlets simultaneously at a stated Pitot tube pressure in psi. • Check that the value you choose is high enough to provide an effective firefighting stream at the highest locations on the vessel, taking into account friction and elevation losses.
