Fluid Mechanics. Volume of a bubble.

AI Thread Summary
The discussion revolves around calculating the volume of a bubble released by a diver at 50 meters underwater, where the initial volume is 1 cm³ and the pressure at that depth is 6 atmospheres. The user suggests using the ideal gas law, P1V1 = P2V2, to find the volume at the surface. They correctly identify that at the surface, the pressure is 1 atmosphere, leading to a calculated volume of 6 cm³ for the bubble when it reaches the surface. The conversation highlights the application of fluid mechanics principles in real-world scenarios. Overall, the calculation demonstrates the effect of pressure on gas volume as it rises.

I was doing some online physics tests with my friend because we were bored and we both got stuck on this question, I was wondering if anyone might be able to help.

A diver at 50metres under the sea (1.02 density) releases bubbles 1cm^3 in volume. What will the volume be when the bubbles reach the surface?

(no temperature mentioned in the question)

Any help appreciated,
Many thanks.

Wouldn't this just be a simple case of P1V1 = P2V2, where 1 = the initial conditions, i.e. a volume of 1 and pressure of 6 atmospheres (one atmosphere for every ten metres of depth and an obvious additional atmosphere so we're working with the total pressure), and P2 = 1. Therefore I get V2 = 6.

I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly

Thread 'What's the most likely cause for this carbon seal crack?'

We have a molded carbon graphite seal that is used in an inline axial piston, variable displacement hydraulic pump. One of our customers reported that, when using the “A” parts in the past, they only needed to replace them due to normal wear. However, after switching to our parts, the replacement cycle seems to be much shorter due to “broken” or “cracked” failures. This issue was identified after hydraulic fluid leakage was observed. According to their records, the same problem has occurred...
