Hi all, There is some great discussion here; thanks! This is exactly where my friends and I got stuck. I'm glad to see smarter people than I are working though it! For reference sake: This idea / problem came from an old (80's?) video that played on public television; it was a video of a...

I had never considered that before...but it makes perfect sense...that is too crazy! Thank you for your patience in answering my questions...it seems common sense was in fact right here, I think I must not fully understand the factors that go into calculating pressure. Thanks again!

So, am I correct is saying the pressure in a barrel with 50 feet of garden hose full of water above would be the same pressure in a barrel with 50 feet of 12 inch pipe full of water above? What about 50 feet of drinking straw full of water above? That's what I can't wrap my head around...

This is where I keep getting lost! In the formula to calculate pressure, Mass isn't a factor, just density of the liquid, gravity, and depth...so, please bear with me, but a follow-up question...if we're factoring in the mass of the liquid above (as makes sense to me)...then, does that mean the...

If the barrel had a lid, and the hose was in a hole in the lid...wouldn't the entire pressure of the barrel increase? (assuming the lid is sealed well, and the junction of the hose to lid was also sealed). Would it be possible to over-pressurize a barrel this way? Assuming the above...

Hello, I have a follow-up question related to water pressure that has been plagueing me for some time: Water pressure is calculated by: P = Density of fluid * acceleration of gravity * height of fluid above. I once saw a professor say he knew of an expierment where he filled a wood...
