Submarine Sinking: Calculate Volume Needed to Flood

In summary, the volume needed to flood a submarine is calculated by multiplying the length, width, and height of the submarine and subtracting the volume of internal compartments and equipment. This calculation can be affected by factors such as the size and shape of the submarine, the water density, and any damage to the hull. While simulations can provide a more accurate estimation, it is important to use accurate and up-to-date information and follow safety precautions to ensure the safety of the submarine and its crew.

Homework Statement


A submarine that weighs 10,000kg in air and has a volume of 12m3 floats in a harbor. How much of its volume do we need to flood in order to just begin sinking it in salt water with a density 1.02 g/cm3?

Homework Equations





The Attempt at a Solution

The first step is to determine what forces are acting on the boat: one is gravity, the other is the buoyant force.
 

Related to Submarine Sinking: Calculate Volume Needed to Flood

1. How is the volume needed to flood a submarine calculated?

The volume needed to flood a submarine is calculated by multiplying the length, width, and height of the submarine. This will give you the total volume of the submarine. Then, you must subtract the volume of the air and any other compartments or equipment inside the submarine that will not be flooded. The remaining volume is the amount of water needed to completely sink the submarine.

2. What factors affect the volume needed to flood a submarine?

The volume needed to flood a submarine can be affected by several factors, including the size and shape of the submarine, the amount and placement of internal compartments and equipment, and the density of the water it is submerged in. Additionally, any damage to the submarine's hull or other structures can impact the volume needed to flood it.

3. How accurate are calculations for the volume needed to flood a submarine?

Calculations for the volume needed to flood a submarine can vary in accuracy depending on the precision of the measurements and the assumptions made about the submarine's internal structure and equipment. It is important to use the most accurate and up-to-date information available to ensure the most accurate calculation.

4. Can simulations be used to calculate the volume needed to flood a submarine?

Yes, simulations can be used to calculate the volume needed to flood a submarine. Advanced computer simulations can take into account various factors such as the shape and size of the submarine, the water density, and the position of internal compartments and equipment. This can provide a more accurate estimation of the volume needed to sink a submarine compared to manual calculations.

5. Are there any safety precautions to consider when calculating the volume needed to flood a submarine?

Yes, there are several safety precautions to consider when calculating the volume needed to flood a submarine. It is important to use accurate and up-to-date information to ensure the safety of the submarine and its crew. Additionally, the calculation should be double-checked by multiple experts to minimize the risk of errors. Safety protocols should also be followed when actually flooding the submarine to prevent any accidents or injuries.
