Pressure

Examples of Pressure in the following topics:

• Physics and Engineering: Fluid Pressure and Force

  • Pressure is given as $p = \frac{F}{A}$ or $p = \frac{dF_n}{dA}$, where $p$ is the pressure, $\mathbf{F}$ is the normal force, and $A$ is the area of the surface on contact.
  • While pressure may be measured in any unit of force divided by any unit of area, the SI unit of pressure (the newton per square meter) is called the pascal (Pa).
  • Pressure is a scalar quantity.
  • The pressure is the scalar proportionality constant that relates the two normal vectors:
  • Pressure is an important quantity in the studies of fluid (for example, in weather forecast).
