BECC Test 5 learn mode questions
A fixed volume of liquid is discharged by a centrifugal pump (TRUE/FALSE)
Answer: False
Explanation: The correct response is False. This item tests whether the statement matches the operating principle in Pumps and Oily Water Separator. Read the key words carefully and connect them to the correct shipboard system or component.
Which centrifugal pump component prevents reverse flow of liquid through the pump?
Answer: Check valve
Explanation: Check valve is the correct answer because it is the component or item that performs the function described in the question. Focus on the job being done, then match it to the proper shipboard term.
What is used to move fluid from one location to another?
Answer: Pump
Explanation: Pump is the correct answer because it is the component or item that performs the function described in the question. Focus on the job being done, then match it to the proper shipboard term.
What centrifugal pump component rotates and causes centrifugal force to act on the fluid ?
Answer: Impeller
Explanation: The correct answer is Impeller. This BECC Test 5 item checks the relationship between the question keyword and the matching Navy engineering component, system, value, or procedure.
What centrifugal pump component prevents overheating of the pump?
Answer: Recirculation line
Explanation: The correct answer is Recirculation line. This BECC Test 5 item checks the relationship between the question keyword and the matching Navy engineering component, system, value, or procedure.
What condition occurs if there are bubbles forming in the pump casing?
Answer: Pump cavitation
Explanation: The correct answer is Pump cavitation. This BECC Test 5 item checks the relationship between the question keyword and the matching Navy engineering component, system, value, or procedure.

The two spur gears in a rotary gear pump are called the gear and the gear?
Answer: Driving & Driven
Explanation: The correct answer is Driving & Driven. This BECC Test 5 item checks the relationship between the question keyword and the matching Navy engineering component, system, value, or procedure.
What type of pump uses the throwing force of a rapidly revolving impeller?
Answer: Centrifugal pump
Explanation: The correct type is Centrifugal pump. This question tests recognition of equipment design, flow arrangement, or component classification used in Navy engineering systems.
To eliminate replacing the impeller or casing due to wearing, what is used inside the pump?
Answer: Mechanical shield
Explanation: Mechanical shield is the correct answer because it is the component or item that performs the function described in the question. Focus on the job being done, then match it to the proper shipboard term.
Which tank stores oily waste prior to separation by the OWS?
Answer: Oily Waste Holding Tank
Explanation: Oily Waste Holding Tank is the correct answer because it is the component or item that performs the function described in the question. Focus on the job being done, then match it to the proper shipboard term.
What is the allowed limit of oil in the overboard discharge if the ship is within 50 miles of land?
Answer: 15 PPM (Part Per Million)
Explanation: The tested value is 15 PPM (Part Per Million). Memorize this number with the exact equipment or procedure named in the question, because similar Navy engineering values can be easy to confuse.
What is used to remove large particulate matter from oil before it enters the OWS?
Answer: Duplex strainer
Explanation: Duplex strainer is the correct answer because it is the component or item that performs the function described in the question. Focus on the job being done, then match it to the proper shipboard term.
What tank receives separated oil from the OWS for later discharge?
Answer: Waste oil tank
Explanation: The correct answer is Waste oil tank. This BECC Test 5 item checks the relationship between the question keyword and the matching Navy engineering component, system, value, or procedure.
What is used to measure the amount of oil in water that is discharged overboard?
Answer: Oil content monitor
Explanation: Oil content monitor is the correct answer because it is the component or item that performs the function described in the question. Focus on the job being done, then match it to the proper shipboard term.
