Q:

Which among the following is not a type of jet engine?

A) Turbojet B) Ramjet
C) Scramjet D) Propulsive jet
 
Answer & Explanation Answer: D) Propulsive jet

Explanation: A jet engine is broadly classified into four types of jet. The four types of jet are turbojet, ramjet, scramjet, and pulse jet. There isn’t anything related to the propulsive jet and thus cannot be the answer.

Q:

Jet propulsion of ship in a very shallow water is needed to_________

A) Avoid sinking of the ship B) Avoid damage of the propeller
C) Avoid current directions D) Avoid surface damage
 
Answer & Explanation Answer: B) Avoid damage of the propeller

Explanation: Jet propulsion of ship in a very shallow water is needed to avoid damage of the propeller. Jet propulsion of ship is less efficient than screw propeller due to large amount of frictional losses developed in the pump and the pipeline.

Q:

Jet propulsion of ship is less efficient than screw propeller due to_______

A) Pressure B) Temperature
C) Frictional losses D) Wear and tear
 
Answer & Explanation Answer: C) Frictional losses

Explanation: Jet propulsion of ship is less efficient than screw propeller due to large amount of frictional losses developed in the pump and the pipeline. Thus, it is rarely used in ships.

Q:

Principle of fluid mechanics works on the utilization of________

A) Accelerating mass B) Volume
C) Work D) Velocity
 
Answer & Explanation Answer: C) Work

Explanation: The Principle of fluid mechanics works on the utilization of useful work. The working is based on the force exerted by a fluid jet striking the surface and moving over a series of vanes about its axis.

Q:

Component of velocity in direction of jet is -VCosθ. What does ‘θ’ indicate?

A) Angle made by jet B) Angle made by jet and outlet tip
C) Angle made by jet and inlet tip D) Tangent angle
 
Answer & Explanation Answer: C) Angle made by jet and inlet tip

Explanation: Component of velocity in direction of jet is -VCosθ. The negative sign indicates the that the taken velocity at the outlet is opposite to the jet of water coming out from the nozzle. ‘θ’ indicates the angle made by jet and inlet tip of the curved plate.

Q:

What is the equation for efficiency of jet propulsion?

A) 2u/(V-2u) B) 2u/(V+2u)
C) 2u/v D) V/2u
 
Answer & Explanation Answer: B) 2u/(V+2u)

Explanation: The efficiency of a jet propulsion of the ship when the inlet orifices are at right angles to the direction of the motion of the ship is given by 2u/(V+2u).
