What would be the hydrostatic pressure near the top of a vertical pipe closed at the top and open on the bottom? Would you calculate the pressure density*gravity*depth measuring depth from the top of the pipe or from its opening at the bottom or the difference between the point of measurement and the top of the pipe? say the pipe was 50 feet tall, and submerged underwater 10 feet, what would the calculation for the pressure 1 foot from the top of the pipe be? d*g*11 or d*g*60? or d*g*1 this isnt homework question. i never did my homework in school anyway. (and it probably shows). im trying to build this. help please?
