I have a piston inside a cylinder. The cylinder has no end on it and the piston is level with the top of it. The area of the piston is 1 square inch. If I put my hand over the top of the cylinder and draw the piston down I will immeadiately be creating a total vacuum. Am I right in thinking that no matter how far I retract the piston there will only ever 14.7 LBS of force on my hand? Will there become a point at which a neat cylinder of my hand gets 'sucked' into the cylinder?
