text: The centrifuge method relies on the following relationship between capillary pressure and gravity:
  where:
  : is the height of the capillary rise
  : is gravity
  : is the density of the wetting phase
  : is the density of the non-wetting phase
  The centrifugal force essentially serves as an applied capillary pressure for small test plugs, often composed of brine and oil. During the centrifugation process, a given amount of brine is expelled from the plug at certain centrifugal rates of rotation. A glass vial measures the amount of fluid as it is being expelled, and these readings result in a curve that relates rotation speeds with drainage amounts. The rotation speed is correlated to capillary pressure by the following equation:  
  where:
  : is the radius of rotation of the bottom of the core sample
  : is the radius of rotation of the top of the core sample
  : is the rotational speed
  The primary benefits to this method are that it's rapid (producing curves in a matter of hours) and is not restricted to being performed at certain temperatures.
  Other methods include the Vapor Pressure Method, Gravity-Equilibrium Method, Dynamic Method, Semi-dynamic Method, and the Transient Method.
