Assuming the experiment is conducted at 1 atmosphere, sea level, then the ambient pressure is 14.7lbs/square inch. In water the pressure increases linearly by 1 atmosphere for every 33 feet of depth. So the pressure 120mm under water is (1 +(120 mm/33 feet)) x 14.7 lbs/square inch. About 15 PSI.

The water pressure at 3 kilometers depth is roughly 300 atmospheres, which is equivalent to around 4400 pounds per square inch (psi). At this depth, the weight of the water above creates significant pressure due to gravity.
The water pressure at 5000 feet depth is approximately 2200 pounds per square inch (psi). This pressure increases by 0.44 psi for every foot of depth.
Divide the difference in pressure by the difference in depth.
The water pressure at a depth of 2.3 miles underwater is approximately 3,216 pounds per square inch (psi). At this depth, the weight of the water above exerts a significant force, creating high pressure conditions that can be challenging for structures and equipment.
At 5,500 feet down, the pressure on the vessel would be 2,458.71 pounds per square inch.
The water pressure at 1000 feet is approximately 433 pounds per square inch (psi). This is because for every 2.31 feet of depth in water, the pressure increases by 1 psi due to the weight of the water column above.
As depth increases, water pressure also increases due to the weight of the water column above exerting a force downwards. The increase in pressure is approximately 1 atmosphere (14.7 pounds per square inch) for every 10 meters of depth.
Pressure in seawater at 100 feet is 44 psi. Or, .44 pounds per square inch per 1 foot. For Fresh water, it is .43 psi per foot.
The pressure at a depth of 5 meters under water is approximately 0.5 atmospheres, which is equivalent to 49 kilopascals. This pressure is caused by the weight of the water above pushing down on the water at that depth.
Pressure = force / area, but > Force (weight) of water = mass * acceleration > Select a depth, choose an area the weight of water is acting on ( say 1 square inch ) calculate the force (weight) of the water column above that area (in pounds) Divide force by area = pressure (pounds per square inch (psi)) Dont forget to add atmospheric pressure (psi) to the answer.
Water pressure increases by about 1 atmosphere for every 33 feet of depth. At 2000 feet depth, the water pressure would be about 60 atmospheres or 882 psi (pounds per square inch). This high pressure can pose significant challenges for deep-sea exploration and engineering.
