the fluid pressure 10 ft under water is
no
Pressure changes very easily. The deeper that you go there is more pressure. For example, when you dive into the ocean, there is not only a whole sky-worth of air pushing down on you, but you are also being pressured by the tons of water above you. On the flipside, when you travel to a greater altitude, pressure decreases. For exapmle, when you climb a mountian, there is less air above you pushing down on you then there is on sealevel.
Hydrostatic head (ft) multiplied by the fluid density, and divided by 2.31 equals PSI. The fluid density of water is 1 at normal temperature (20C).
10 ft by 27 ft = 10 ft x 27 ft = 270 sq ft
Pressure is directly proportional to depth. The equation used is for hydrostatic pressure: P = Po + dh Where P = pressure, Po = initial pressure at surface, d = density of the fluid, and h = height to the free surface (or depth). In diving, Po is usually the atmospheric pressure. This is the only thing that elevation affects, as sea level air pressure is higher than the air pressure at higher elevations. The density of sea water is generally accepted as 64 lbs/cu ft. There is variation, but usually not enough to be meaningful, unless you are diving in a very high salinity location, like the Dead Sea, in which the salt content is so high that the density is considerably higher. For most purposes, atmospheric pressure at sea level is accepted to be 14.7 lbs/sq in (14.7 psi), or 2116.8 lbs/sq ft (2116.8 psf). Diving in sea water then, the equation becomes: P = 2116.8 lbs/sq ft + 64 lbs/cu ft x h. Then, at the surface, h = 0, and P = 2116.8 psf = 14.7 psi. At h = 10 ft, P = 2116.8 + 64 x 10 = 2756.8 psf = 19.1 psi. At h = 33 ft, P = 4228.8 psf = 29.4 psi. At h = 100 ft, P = 8516.8 PS = 59.1 psi. And so on. The general rule-of-thumb for sport/recreational diving is that the pressure increases by 14.7 psi (1 atmosphere) for every 33 ft of depth. So that at 100 ft, the pressure is 58.8 psi (4 atmospheres). (Remember that you start at the surface at 1 atmosphere.)
The pressure of rarefied air is strongly different from the pressure of a big layer of water.
"If you are 15 ft. under water, the pressure will be the same no matter how large the body of water is" is a true statements about fluid pressure.

'Hydrostatic Pressure' is the Term used for 'the force exerted by a body of fluid at rest. The pressure increases with increase in depth.There are two ways to Calculate water (clean water) pressure at any depth (both yields almost same results):1. The Hydrostatic pressure of water is 0.433 Psi/ft (Pounds per square inch Per feet). So at 5000 feet, the pressure is: 0.433 Psi/ft. * 5000 ft = 2165 Psianother way to go about it is:2. Water pressure increases at 14.7 psi every 34 feet depth. Thus Pressure at 5000 ft will be: (5000 ft / 34 ft) * 14.7 psi = 2162 Psi.
12 ft * 10 ft * 10/12 ft = 10 cubic feet.12 ft * 10 ft * 10/12 ft = 10 cubic feet.12 ft * 10 ft * 10/12 ft = 10 cubic feet.12 ft * 10 ft * 10/12 ft = 10 cubic feet.
The rate is (44.4 - 29.55) / 33 which is 14.85 psi/33 feet = 0.45 psi/ft
