28 gru 2020 · The SI unit of pressure is the Pascal (Pa) , where 1 Pa = 1 N/m 2, i.e. one Newton per square meter. The Newton is the unit of force, so it’s easy to see that the Pascal meets the requirements for a unit of pressure.
The base units of surface tension are Newtons per meter (N/m) in SI units or pounds per foot (lb/ft) in USC units. The Young-Laplace equation describes the pressure difference across a curved liquid-gas interface resulting from surface tension.
The Pressure under 1 foot of water is $12 inch^3 \times 0.036 pounds/in^3\times 386 inches/s^2$ which gives me $166.75~\text{pound-force per square inch}$. However, various internet references tell me that 1 foot of water exerts $0.43 \text{ psi}$.
Some Pressure Levels. 10 Pa - the pressure below 1 mm of water. 1 kPa - approximately the pressure exerted by a 10 g of mass on a 1 cm2 area. 10 kPa - the pressure below 1 m of water, or the drop in air pressure when moving from sea level to 1000 m elevation.
In SI units, the unit of pressure is the Pascal (Pa), which is equal to a Newton / meter 2 (N/m 2). Other important units of pressure include the pound per square inch (psi) and the standard atmosphere (atm). The elementary mathematical expression for pressure is given by: \[\mathrm{pressure=\dfrac{Force}{Area}=\dfrac{F}{A}}\]
Underwater divers use the metre sea water (msw or MSW) and foot sea water (fsw or FSW) units of pressure, and these are the units for pressure gauges used to measure pressure exposure in diving chambers and personal decompression computers.
