By the application of the jet propulsion principle, a ship is driven through water. A jet of water which is discharged at the back (back called stern) of the ship, exerts a propulsive force on the ship.The ship carries centrifugal pumps which draw water from the surrounding sea. This water is discharged through the orifice provided at the back of the ship in the form of a jet. The reaction of the jet coming out at the back of the ship propels the ship in the opposite direction of the jet. The water from the surrounding sea by the centrifugal pump is taken by the following two ways:-

1) Through inlet orifices which are at right angles to the direction of the motion of the ship and

2) Through the inlet orifices, which are facing the direction of motion of the ship.
