I have come to understand the basics of Pascal's Principle/Hydrostatic pressure, but there is one scenario I am looking for help with.
If I have a piston at the bottom of a chamber of water, and I want to push the piston up to lift the water, I understand that I need to exert a greater PSI on...
I don't know the velocity. The piston will only move up as quickly as the water can exit the top. I can't just assign an arbitrary velocity to the piston, can I?
As for the PSI of the water coming out the top of the pipe... I must admit I have a bit of confusion. 2000 lbs. is being...
I am trying to figure out the flow rate (gallons per minute) and PSI of the water just as it exits the top of the pipe. Is it possible to figure out these out given the information in the diagram?
I'm going to steal a picture that was used in a different thread in this forum.

I watched an MIT video of professor Walter Lewin, who used these very same...
Part 1 - Question About Torque Of Lever Arm in a 1st Class Lever
Homework Statement
A little while back I posted a question about incorporating the torque of a uniform mass and dimension lever arm into the principle of a 1st class lever.
Here is the thread for reference...
My original formula, that did not include the weight of the lever, was...
F1 x 2 feet > F2 x 8 feet
As you can see, the lever is 10 feet long, and I want to lift the long side of the lever using the short side of the lever (hence, the ">" sign).
The center of mass of the entire lever...
In trying to solve a problem, I was using the simple F1D1 = F2D2 as the balance point of a lever. My limited physics knowledge knew no better.
My hypothetical involved using the "short side" of a lever to lift a weight on the long side of a lever.
After thinking about it... I realized I...
I guess, what I am really looking for is a reference.
I have exhausted Google and the Phone Book. I have contacted people in the UConn Mechanical Engineering department (still waiting to hear back). I have posted on Craigslist, talked to mentors via Score.org, looked on freelance websites...
Hello,
I reside in Connecticut and have designed a device (on paper only) that would solve a problem I (and many others) deal with.
I am not an engineer, nor am I going to school to be one. I just used my brain a little, and came up with a possible solution.
A major component of the...
