Okay, that helps a lot! I wish I could thank you for helping me in a way other than just saying thanks so much! I really appreciate the time you took to answer each of my questions and doing so in a clear and polite way. You're truly an asset to this forum.

What's the theory behind the ceiling pushing down with pressure equal to the long column of water? Where can I read about why that occurs and why it is equal? Thanks for the quick responses by the way. This was driving me nuts. It's clear the plates change the system then if the ceiling is...

Hmm, but the pressure the ceiling puts on the fluid is not that great because it is only a result of the long column of vertical water. The area of the ceiling is quite large so the distribution of the forces from the vertical column would make the force is exerts rather small?Yes, the plates...

How is hydrostatic pressure not a function of the shape of the container? My professor says that the pressure P2 is the same for the figures on the right and left. How does the area of the two sections not matter at all? Clearly, if a plate is inserted of negligible mass, thickness, and...

Okay, I think I am going to not pursue this any further. I appreciate all the help but it's now beyond the scope of my abilities to handle. Thanks for all the replies. -Paul

Couldn't you turn the KwH or the Joules into Kinetic Energy without it? (1/2 mv^2)?

Well, my idle fuel consumption is the green circle since my car basically idles at 1000 rpm. Does that mean idling, it is just as efficient as it is at 6000rpm (aka, not really that efficient?) At 2000rpm, that's my prime efficiency, correct?

Well, after finding a few racing power curves (sorry I don't use a drag racer to climb up hills), I got a hold of a 2001 Dodge minivan engine power curve. Not being totally familiar, does anyone have any idea how to use it? http://www.jnjhome.net/dodge/images/powercurves.gif I assume I'd...

Is it possible to find energy curves for the gears for ground and slopes? I suppose it probably isn't and would be company "secrets." Hmm.

Well, even though I am not accounting for drag, the higher speed of the second car would make it have to work harder so things like the amount of gas in the tank are not significant either. Although it's the little things about physics, isn't it?

Is there any way to prove that speeding up before a hill in a car will save you gas compared to maintaining your speed on the hill? Here is the situation: Notice, the one car maintains 10m/s throughout while the second car accelerates to 20m/s on the flat part. Both cars will have...
