Under Aquatic Relation with Science | Force Pressure and Density

Science of Underwater Diving

The effects of diving on the human body are caused by the operation of certain physical laws, in particular the physical properties possessed by liquids and gases.

Underwater, the human body operates in a completely different environment, in which it is exposed to much greater pressures than it experiences at the surface. It is necessary, therefore, to consider carefully the meanings of the terms force, pressure, and density as applied to liquids and gases.

Force = Mass x Acceleration (and is measured in Newton’s (N)

Pressure = Force / Area (measured in bars or N/m2)

Density = Mass / Volume (unit=kg/m3)

Conclusion:

The science of underwater/scuba diving involves understanding the effects of diving on the human body, which is influenced by the physical laws governing liquids and gases. When deep sea diving, the human body encounters increased pressure due to the underwater environment.

To comprehend this phenomenon, it is important to carefully consider the definitions of force, pressure, and density as they pertain to liquids and gases. Force is determined by multiplying mass and acceleration, and it is measured in Newton’s (N). pressure is calculated by dividing the force by area and is measured in bars or Newtons per square meter (N/m²). Density is the ratio of mass to volume and is expressed in kilograms per cubic meter (kg/m³). Understanding these concepts helps to explain the pressure experienced by the walls of the container during underwater scuba/deep sea diving.
