1. A relay pumper must maintain ______ psi at compound (intake). A. 10 psi B. 20 psi C. 30 psi D. 40 psi Rationale: Maintaining 20 psi ensures that the intake side does not experience cavitation and maintains a safe supply. 2. An attack pumper in a relay operation should be operating in what pump mode? A. Volume B. Pressure C. Idle D. Draft Rationale: Pressure mode ensures the attack lines get high enough pressure to be effective during firefighting operations. 3. A relay pumper in a relay operation should be operating in what pump mode? A. PSI B. Draft C. RPM D. Idle Rationale: Relay pumpers use RPM (engine speed) to regulate output, especially when supplying water to another pumper. 4. When approaching a hazmat incident, apparatus and personnel should approach in what manner? A. Downhill and downwind B. Uphill and downwind C. Downhill and upwind D. Uphill and upwind Rationale: Approaching uphill and upwind minimizes exposure to hazardous materials. 5. What type of system relies on water at a high elevation? A. Direct system B. Combination system C. Gravity system D. Pumped system Rationale: A gravity system uses elevation to create water pressure naturally. 6. In order to reduce friction loss, we can ____________. A. Decrease pressure B. Shorten hose length C. Increase hose diameter D. Add more appliances Rationale: Larger diameter hoses reduce friction by providing more internal space for water flow. 7. The water system in most municipalities is a: A. Direct system B. Gravity system C. Combination system D. Intermittent system Rationale: Most systems combine gravity and pump-assisted pressure for reliability. 8. If a hydrant receives flow from only one direction, it is called a: A. Loop hydrant B. End-flow hydrant C. Single main hydrant D. Dead end hydrant Rationale: Dead-end hydrants receive water from only one direction, limiting flow. 9. Public water systems commonly use what type of valve? A. Indicating valve B. Gate valve C. Non-indicating valve D. Ball valve Rationale: Non-indicating valves are common in underground systems where the open/closed status isn't externally visible. 10. The counterforce of a nozzle is called: A. Back pressure B. Nozzle drag C. Recoil D. Nozzle reaction force Rationale: Nozzle reaction is the force exerted backward when water exits a nozzle. 11. A flow meter should be accurate within: A. ±1% B. ±2% C. ±3% D. ±5% Rationale: Flow meters are calibrated to be accurate within 3% to ensure reliable readings. 12. Condensed Q cannot be used with which unit system? A. Imperial B. SI C. Metric D. Customary Rationale: The Condensed Q method uses imperial units and isn’t compatible with metric measurements. 13. The operation of a centrifugal pump is dictated by the: A. Pump casing B. Shaft C. Impeller D. Housing Rationale: The impeller is the key component that creates centrifugal force to move water. 14. A laterally mounted pump is also called a: A. Rear mount B. Side pump C. Midship D. Top-mount Rationale: Midship pumps are mounted laterally near the middle of the vehicle. 15. A vacuum gauge is also known as: A. Suction gauge B. Intake pressure gauge C. Drafting gauge D. Master intake gauge (compound) Rationale: The master intake (compound) gauge reads both pressure and vacuum levels on the intake side. 16. A hydrostatic test of a fire pump must hold how much psi? A. 250 psi B. 300 psi C. 500 psi D. 700 psi Rationale: Fire pumps must withstand 500 psi during hydrostatic testing to ensure integrity. 17. A strainer in a drafting operation should be how far below the water surface? A. 1 ft B. 1.5 ft C. 2 ft D. 3 ft Rationale: A 2-foot clearance prevents vortexing and ensures effective water draw. 18. NFPA requires how many sides available for dumping during shuttle operations? A. 2 B. 3 C. 1 D. 4 Rationale: Right, left, and rear sides must be accessible for efficient water shuttle operations. 19. What are the three components required for foam operations? A. Water, air, soap B. Water, pressure, foam concentrate C. Air, water, foam concentrate D. Foam, pressure, oxygen Rationale: Foam generation needs water, foam concentrate, and air. 20. What NFPA standard deals with fire pumps and engines? A. NFPA 1001 B. NFPA 1962 C. NFPA 1901 D. NFPA 1582 Rationale: NFPA 1901 specifies requirements for fire apparatus including pumps. 21. A 1" 7/8 smooth bore nozzle on a deck gun will flow how much at what pressure? A. 1000 gpm at 100 psi B. 800 gpm at 70 psi C. 900 gpm at 80 psi D. 950 gpm at 90 psi Rationale: Standard flow at 80 psi for a 1 7/8” tip is approximately 900 gpm. 22. A transfer valve in a two-stage pump is used for: A. Diverting intake flow B. Isolating discharges C. Regulating temperature D. Controlling water flow between stages Rationale: The transfer valve switches the pump between volume and pressure modes. 23. What number is used to convert inches of mercury (Hg) to feet of lift? A. 1.10 B. 1.13 C. 1.25 D. 1.30 Rationale: 1 inch of Hg equals approximately 1.13 feet of water lift. 24. A fog nozzle flows its rated GPM at what pressure? A. 50 psi B. 80 psi C. 100 psi D. 125 psi Rationale: Fog nozzles are typically rated to flow at 100 psi for optimal stream and reach. 25. The hand method for 2½" hose friction loss is based on which formula? A. FL = Q² B. FL = 2Q² + Q C. FL = Q × L D. FL = Q + C Rationale: The hand method formula for 2½" hose approximates FL based on flow (Q).
