A ship is floating on a lake. Its hold is the interior space beneath its deck; the hold is empty and is open to the atmosphere. The hull has a hole in it, which is below the water line, so water leaks into the hold. The effective area of the hole is 4.8 × 10-3 m2 and is located 2.5 m beneath the surface of the lake. What volume of water per second leaks into the ship?


  1. Answer:

    33.4 litres/sec



    hole area A = 0.0048 m²

    Velocity is given by:

    V =√2gh = √(2 x 9.8 x 2.5) = 7 m/sec

    flow = A x V = (0.0048)(7) = 0.0334 m³/sec

    0.0334 m³/sec => 33.4 litres/sec
