Permeability measurement Liquid permeability : The liquid permeameter is used for determining the liquid permeability of consolidated core section . Permeability measurement with liquid are made by determining the time required for a given volume of liquid to flow the through a core of known dimension at an observed pressure and temperature . These data ,provided by the instrument ,together with the viscosity of the fluid , are used to calculate Liquid permeability , the basis for this calculation is the application of darcy's law for linear flow . P A L q K l * * * Steps of this method: 1. Prepare the sample by known dimensions. 2. put the core in the sample cell. 3. it compress on the sample by over burden pressure. 4. it pump fluid for sometime. 5. by knowing both volume of liquid , the time required it then calculate the permeability by using :

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
