You can lift a locomotive or a house with 1 psi, if the pressure is applied over a large enough area.
This is a kind of trick question. In a closed static system containing fluid, pressure is equal everywhere. This is called the Law of Pascal. One can use this principle to lift a car with a finger. Fill a tank with water and have a car float on a platform. Now make a hole in the tank and connect a tube to it. By preventing the tube to leak, you have to apply a certain pressure, which may be smaller than 1 bar. If you increase the pressure, either by hand or possibly by blowing the tube, you can lift the car. Not so much with a short tube, but more with a long tube. The higher pressure in the tube will push the water back in the tank and cause the water in the tank to rise with the car on top of it.
Like any simple machine, it spreads the work over a greater distance. For example, if you want to raise a load five feet, by using a 30° inclined plane, you spread the same work over ten feet, so only half as much force is needed.
Assuming you need a metric ton, that's 1000 kilograms. To lift that, you need a FORCE of 9800 newtons. Force is related to pressure by: pressure = force / area, so the answer to the original question would depend, over what area the force is applied.
30 litres of water weighs about 65 pounds, so a fit person should be able to lift it.
To calculate head pressure in psi from a head height given in feet you multiply by 0.434. 15 x 0.434 = 6.51 psi
Differences in air pressure, an angle of attack, and lift
Seals on the hydraulic cylinder keep the pressure, which are needed to lift the suspension in the air. If they leak, they lose pressure and won't be able to lift the vehicle.

You can lift a locomotive or a house with 1 psi, if the pressure is applied over a large enough area.
That depends on the water pressure and the surface area that the water is pushing against.
first i cant solve this because i don't have (X Saltwater and X type of vacuum+ Pressure of it) but i do have the right idea.. 1: Find the greatest amount of force that the vacuum can lift or the psi. 2: figure out the amount and the weight of salt water you want to lift 3: figure out if the vacuum can even have enough lift with a 6in tube 4: make sure all the tubes are sealed good 5: test it out.. Hope that helps! And Happy testing! :]
It generally takes 2 feet of water to lift/move/carry a vehicle. Be safe- Turn Around, Don't Drown!
because the water pressure takes up some of the weight as you lift it in the water
Pressure = force / area. Calculate the equivalent force in newton, then divide by the area. Answer is in pascal.
yep
