pressures

• Kilopascal (kPa).


  Kilopascal (kPa): A unit of pressure equal to 1,000 pascals. It is commonly used in engineering and scientific contexts to measure pressure, especially in applications involving fluids and gases.
• Pounds per square inch (psi): 


  A unit of pressure commonly used in the United States and other countries that follow the imperial system. It represents the amount of force exerted by one pound-force acting on an area of one square inch.
• Pascal (Pa) 


  It is defined as one newton per square meter, representing the pressure exerted by a force of one newton acting uniformly over an area of one square meter.
• Pressure head: 


  The height of a column of fluid required to produce a specific pressure at its base.
• The pressure area: 


  refers to the surface or boundary where the hydrostatic pressure is exerted.
• Fluid column:


  A vertical column of fluid in a container, where the pressure at the bottom is greater than at the top due to the weight of the fluid.
