2 Answers. Consider this diagram showing the three columns you describe all connected to the same body of water: Your question asks whether the three pressures P1 P 1, P2 P 2 and P3 P 3 will be the same. The answer is obviously yes, because the columns are all connected to the same body of water.
Oct 21, 2024 · At the Earth’s surface, the air pressure exerted on you is a result of the weight of air above you. This pressure is reduced as you climb up in altitude and the weight of air above you decreases. Under water, the pressure exerted on you increases with increasing depth.

The density of water at 4 oC is 1000 kg/m3 . The pressure acting in water at 1 m can be calculated as p = ρ g h = ( 1000 kg/m3 ) ( 9.81 m/s2) (1 m) = 9810 Pa
The density of water at 32 o F is 1.940 slugs/ft3 . The pressure acting in water at 3 ft can be calculated as p = ρ g h = ( 1.940 slugs/ft3 ) ( 32.17405 ft/s2) (3 ft) = 187.3 lb f /ft2(psf) = 1.3 lb f /in2(psi) 1. pressure converter
Ocean pressure varies with depth and position (latitude) on earth. 1. 1 Pa = 10-6 MPa = 10-3 kPa = 10-6 N/mm2= 10 -5 bar = 0.1020 kp/m2= 1.020x10-4 m H2O at 4°C/39°F = 9.869x10-6 atm = 0.004 in H2O= 1.450x10-4 psi (lbf/in2) = 0.02089 lbf/ft2(psf)
The average pressure p due to the weight of the water is the pressure at the average depth h of 40.0 m, since pressure increases linearly with depth. The force exerted on the dam by the water is the average pressure times the area of contact, F = pA.

To define the pressure at a specific point, the pressure is defined as the force dF exerted by a fluid over an infinitesimal element of area dA containing the point, resulting in p = \(\frac{dF}{dA}\).
The pressure from the weight of a column of liquid of area A and height h is . The most remarkable thing about this expression is what it does not include. The fluid pressure at a given depth does not depend upon the total mass or total volume of the liquid.
