Aux 1 Unit 10 Q8

1 / 10

What is the primary component used to generate water flow in a transverse water jet thruster?

B) An impeller driven by an electric or hydraulic motor

C) A manually operated pump

D) A rudder blade

A) A hydraulic piston

2 / 10

What is the purpose of the tunnel in a transverse water jet thruster system?

A) To house the impeller and nozzle, guiding the flow of water across the vessel to create lateral thrust

D) To store water for ballast

C) To decrease the vessel's draft

B) To increase the vessel's speed

3 / 10

How is thrust generated in a water jet thruster?

B) By using an impeller to draw in water and expel it at high velocity through a nozzle

A) By rotating the propeller at high speeds

D) By lowering the vessel's draft

C) By increasing the vessel's engine power

4 / 10

What role does the nozzle play in the operation of a water jet thruster?

B) It directs the flow of water to create thrust in the desired direction.

C) It increases the temperature of the water.

D) It filters debris from the water.

A) It reduces the water pressure.

5 / 10

Why is water expelled at high velocity in a water jet thruster system?

A) To cool the vessel's engine

C) To increase the vessel's draft

D) To reduce the vessel's weight

B) To generate a sufficient reactive force that propels the vessel in the opposite direction of the expelled water

6 / 10

Which principle of physics primarily governs the operation of a water jet thruster?

B) Bernoulli's principle

D) The law of buoyancy

C) Newton's third law of motion: for every action, there is an equal and opposite reaction

A) Conservation of energy

7 / 10

Which of the following is a key advantage of using a transverse water jet thruster in a vessel?

B) It allows for precise lateral movement, making docking and maneuvering in tight spaces easier.

D) It eliminates the need for a rudder.

A) It provides propulsion at high speeds.

C) It increases fuel efficiency at cruising speeds.

8 / 10

How is the direction of thrust controlled in a transverse water jet thruster?

D) By adjusting the vessel's rudder

A) By changing the speed of the vessel

B) By rotating the entire thruster assembly

C) By using a nozzle that directs the water flow to either side of the vessel

9 / 10

Where is the water intake typically located in a transverse water jet thruster system?

B) On the sides of the vessel

C) On the deck of the vessel

A) At the bow or stern of the vessel

D) On the bottom of the vessel

10 / 10

In a transverse water jet thruster, what role does the motor play?

A) It cools down the water before it is expelled.

D) It increases the vessel's speed.

C) It adjusts the angle of the propeller blades.

B) It powers the impeller, which generates the water flow necessary for thrust.
