Question

Through inlet orifices, which are facing the direction of motion of the ship, the water from the sea can be taken by the pump.

(a) True

(b) False

This question was addressed to me in examination.

This is a very interesting question from Force Exerted by a Jet on a Series of Vanes topic in chapter Impact of Jets and Jet Propulsion of Fluid Mechanics

Answer 1

The correct choice is (a) True

To explain I would say: Through inlet orifices, which are facing the direction of motion of the ship, the water from the sea can be taken by the pump. We can also take the sea water from the pump when the inlet orifices are at right angles with respect to the motion of the ship.
