Pressure is defined as force per unit volume.
Pressure is measured in pascals (Pa).
A drawing pin placed pin-side down exerts less pressure than when placed head-side down.
The pressure exerted by a snowmobile with a weight of 800 N and an area of 0.20 m² is 4000 Pa.
The atmospheric pressure at sea level is typically around 100 kPa.
The pressure in fluids acts only in one direction.
As depth increases in a liquid, the pressure decreases.
The pressure at 10 meters below the surface of water is approximately 200 kPa.
Scuba divers can safely dive beyond 20 meters without taking extra precautions.
The pressure exerted by a fluid depends on the area of the container.
Early submarines had limited underwater endurance due to battery capacity.
The pressure hull of a submarine is designed to withstand atmospheric pressure only.
The pressure at a given depth in a fluid is the same regardless of the shape of the container.
The total pressure on a diver at 10 meters depth is about 100 kPa.
The change in pressure below the surface of a fluid can be calculated using the equation Δp=ρgΔh.
