Question - A 1450 Kg submarine is submerged at 160 m below the surface of the water. The diameter of the submarine is 5 m and its length is 25 m, the submarine has a door with dimensions 0.7 in and 2.5 m. The submarine starts to move through the water at a constant depth and with an acceleration. Velocity of submarine, V = 40 km/h.
It is required to search, find and calculate the following:
All the pressures and forces acting on the submarine in the following two cases:
a) When the submarine is not moving
b) When it is moving (in this case assume the acceleration as appropriate. Hint: You need to do a search about submarines to find this out)
Note: When solving (a) and (b) you should take into your account the dimensions of the submarine indicated on the figure and within text and this is for both cases of design)
The hydroststic force (in newtons) that is applied on the door to open it outwards if the water pressure is the only force keeping it closed. (Assume g = 9.81 m/s2. density of water = 1000 Kg/m3.
The hydroststic force (in newtons) that is applied on the circular o.S in in diameter window indicated in the figure. Get the line of action of the force. The beginning of the window is 2 in from the top of the submarine.
