how much pressure is on you (per square inch) at 1000 feet of sea water?

p=F/A \n\nSo, you have the pressure of the atmosphere pluss the weight of the water above you.  Which is usually figured as a cylinder.  Hope that helps.

The normal equation for water pressure is P=rho*g*h\n\nwhere g is the acceleration of gravity, rho is density, or\nmass per unit volume and h is the depth of the water. \n\nSince you want to compute in avoirdupois units for some incredible reason, you are going to have to deal with some confusion. The density of water in avoirdupois units is actually m/L^3 where m is in slugs, and L is in feet. \n\nHowever, we know that the weight of a cubic foot of water is 62 lbs. A lb is a unit of force, and F=mg, so \nm=F/g=\n62 lbs/(32 ft/sec/sec)=\n62/32 slugs. \n\nThen in your equation, \n\nP=rho*g*h\n=(F/g)/(L^3)*g*h\n=(F/L^3)*g*h/g\n\nNow substituting, F/L^3=62 lb/ft^3\ng=32 ft/sec/sec\nLet h=50 feet, say\n\nthen P=(62 lb/ft^3)*50ft\n=62*50lb/ft^2\n=3100 lb/ft^2\n\nI do not understand how you put h in meters and somehow ended up with an answer per square inch.\n\nIf you want to convert this to square inches, then\n\n3100 lb/ft^2 *(1ft/12in)^2=3100/144 lb/in^2\n\nIf you want to have h in meters, I will leave that as an exercise to the reader.

Standard sea level barometric pressure is 1013 Millibars. When the needle goes above this, it indicates a High pressure. When the needle drops below, it indicates Low pressure.\nGo to a weather page like http://www.wunderground.com/global/CI_Index.html\nIt will tell you the pressure.

Psf (pounds per square foot) is a pressure unit, Newton is a force unit, so there is no equivalent.  But 0.224808943 pound = 1 Newton, and 1 foot = 0.3048 meter, so that's enough info to convert 8000 psf to Newtons/meter^2, which is a pressure unit.  I googled the conversion, 8000 psf = 383042.072 Newtons/meter^2.  How do you google conversions?  Just enter "8000 lb/ft^2 to newton/m^2".

That depends on the depth. For each 27.68" of liquid water, there is an increase of 1 psi. This would be affected slightly by anything disolved in the water, such as salt in the oceans. Water vapor in the atmosphere is also sometimes included in the term hydrosphere. Pressure at the Earth's surface is figured as 14.7 psi in common usage, which accounts for the difference in psi(a)

Actually standard pressure at sea level is taken to be 14.7 lbs/in^2. \n\nLots of things are factors in air pressure: \n\nAltitude of observations \n\nHeight of air column\n\ndensity of air, depending on temperature, and gas constitutents (constituents usually fairly slowly varying, but temperature varies rapidly)\n\nStrength of gravitational field\n\nTidal forces (small but measurable)\n\nLocal topography (orographic effects)\n\nair motion (usually driven by density differences, which are usually connected with tempearture). \n\n\n\nProbably the biggest factors are temperature, and altitude.

If you mean the pressure at a certain depth from the surface, then no, the area of the column is not important, only the height of water.

Yes you are right to subtract the water pressure from the total pressure.\n\nThen use p1v1/t1 = p2v2/t2\n\nSTP is p2v2/t2\n\nSTP = 1 atm and 0C or 273K\n\nSolve for V2.\n\nKeep units the same on both sides!

Fluid Pressure= weight density x (times) depth\n\nFl. p.= 10,000 kg/m^3(thats the weight density of water) x 15 m\n\nFl. p.= 150,000 m^2 (because one m cancels)\nHope this helps!

true - high sustained pressure and a signifigant distance to any pressure disturbance or variation

It depends on where you live, and at what elevation you live at. Some places, especially higher elevation areas such as Colorado, Wyoming, etc., have a higher average pressure than other lower places such as Florida. The average pressure at sea level is 29.92, so 30.49 is probably high for your area, unless you live above 2000-3000 ft. I know my barometer only goes to 30.70. You must have dry, cold weather. Maybe a cold front just came through.\n\nOops. Higher elevations don't have higher pressure. They have lower pressure. Sorry. \nAlso, the answer after me is dead wrong. I don't have any idea where he gets 39.37. If you look at the link, you can easily see that the average sea level pressure is 29.92. If the pressure was 39 inches of mercury, we would all have horrible migraines, and something bad would happen to our weather system. 30.49 inches is high pressure. 26.something is the lowest pressure recorded. I don't think pressure has gotten higher than 30.75

It depends on the pressure and temperature of the water so the previous answer is limited to only one condition.
