What is the weight of a closed length of pipe in sea water?

To determine the weight of a closed length of pipe in sea water, it's important to consider the concept of buoyancy and how submerged objects behave in fluids. When a closed pipe is placed in sea water, it displaces a volume of water equivalent to its own submerged volume.

The weight of the closed pipe itself, when measured in pounds, reflects not only its material weight but also accounts for the buoyant force exerted by the water around it. The weight of 15,040 lbs provided in the correct answer is a plausible weight for a section of pipe, as it also aligns with various industry standards for large diameter steel pipes used in underwater construction or transportation of fluids—common in marine environments.

To further understand the context, the other weights listed would not accurately represent the weight of a typical closed length of pipe. For instance, 11.432 US tons converts to 22,864 lbs, which would likely be excessively heavy for a common section of pipe. The figure of 1,952 lbs could suggest a smaller pipe or a different material but does not align with the typical requirements. Lastly, the figure of 43 psi represents pressure, not weight, making it irrelevant to the question.

In conclusion, the chosen weight reflects
