About 415psi at 900ft
The pressure at a depth of 200 feet underwater is approximately 86.5 pounds per square inch (psi). This is because pressure increases by 0.433 psi for every foot of depth in water. So, at 200 feet deep, the pressure is 200 ft * 0.433 psi/ft = 86.5 psi.
The pressure of water increases about 0.445 psi per foot of depth. If we "zero" our meter so we have "no" pressure at the surface (ignoring the normal 14.7 psi of air pressure at sea level), at 18 feet we will have 0.445 psi/ft times 18 feet, which is 8.01 psi, or right at about 8 psi.
The pressure of water at a depth of 10000 ft is approximately 4330 psi (pounds per square inch). This is calculated using the formula P = ρgh, where P is the pressure, ρ is the density of water, g is acceleration due to gravity, and h is the depth of the water.
The water pressure at 20 feet deep would be approximately 8.6 pounds per square inch (psi). This pressure increases by 0.43 psi for every additional foot in depth due to the weight of the water above.
Average density of seawater is 1.025, so pressure gradient is approximately 0.444 psi/ft as sea level. At bottom, the pressure is approximately 2235 psia or slightly higher, perhaps 2300 psia.
To convert a height of 33.11 feet to pressure in psi (pounds per square inch), you can use the formula that relates height in feet of water to pressure: 1 foot of water is approximately equal to 0.4335 psi. Therefore, 33.11 feet of water would be approximately 33.11 ft × 0.4335 psi/ft, which equals about 14.35 psi.
'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.
The pressure is only dependent on the height of water above the measuring point. 1 psi corresponds to a height of 2.3 ft, so 8 ft = 3.5 psi The pressure is only dependent on the height of water above the measuring point. 1 psi corresponds to a height of 2.3 ft, so 8 ft = 3.5 psi
Every 2.3077 feet of water in a column increases the water pressure at the bottom of the column by 1 pound per square inch.A 39 foot column of water with a pressure of 120 psi at the base will have a pressure exerted on its top surface of 103.1 psi.39 ft/ 2.3077 ft/1 psi = 16.9 psi ; 120 psi -16.9 psi = 103.1 psievery meter of water in a column increases the pressure at the base of the column by 0.1 kg./ sq. cm (or 1 kilopascal)A 12 meter column of water exerts a pressure at its base of 12 kPa. (or 1.2 kg/sq. cm)
30ft rise = 13 psi (pressure is 13 psi higher at bottom of a 30ft column that at the top). Water Pressure = .433 psi per ft for a column of water at 62 degrees F.
The pressure at a depth of 200 feet underwater is approximately 86.5 pounds per square inch (psi). This is because pressure increases by 0.433 psi for every foot of depth in water. So, at 200 feet deep, the pressure is 200 ft * 0.433 psi/ft = 86.5 psi.
10 feet x 0.433 psi/ft = 4.33 psi at the base of the cylinder.
This depends on what your target pressure is. If the height of the pipe is H in feet, the pressure at the bottom of the pipe from the column of water is 0.036127292 * H * 12 where 0.036127292 is the density of water in lbs/in^3. Thus, if your initial water pressure is I, the pressure at H feet will be I - 0.036127292 * H * 12 So you will have Height | Pressure +--------- 0 ft | 40 psi 10 ft | 35 psi 20 ft | 31 psi 30 ft | 27 psi 40 ft | 23 psi 50 ft | 18 psi 60 ft | 14 psi 70 ft | 10 psi 80 ft | 5 psi 90 ft | 1 psi 100 ft | 0 psi One will be required above 90 ft. You'll probably want one above 40 ft. Derivations: eq means equals. This wiki eats equals signs.

At 99 feet below the surface, the total pressure on a diver can be calculated using the formula: total pressure = atmospheric pressure + (depth in feet × 0.433 psi/ft). The atmospheric pressure at sea level is approximately 14.7 psi. Thus, the total pressure at 99 feet is about 14.7 psi + (99 ft × 0.433 psi/ft) = approximately 14.7 psi + 42.8 psi = 57.5 psi. Therefore, the total pressure on a diver at that depth is approximately 57.5 psi.
The pressure of water increases about 0.445 psi per foot of depth. If we "zero" our meter so we have "no" pressure at the surface (ignoring the normal 14.7 psi of air pressure at sea level), at 18 feet we will have 0.445 psi/ft times 18 feet, which is 8.01 psi, or right at about 8 psi.
The water pressure at the bottom of the pipe can be calculated using the formula P = ρgh, where P is the pressure, ρ is the density of water (1000 kg/m³), g is the acceleration due to gravity (9.81 m/s²), and h is the height of the pipe (188 ft = 57.3 m). Plugging in the values, the pressure at the bottom of the pipe would be approximately 56,700 Pa, or about 8.23 psi.
For water, a 60 ft vertical change is equivalent to about 26 psi change. So if the pressure is 60psi at the bottom, it will be 34 psi at the top. See related link.
