3. Absolute permeability of a core sample is being measured by water flooding. The core sample is mounted in a transparent oylindrical tube, as shown in the figure below, and the air-water surface is monitored as funetion of time. The tube is placed in a vertical position and the water is assumed to flow through the whole.core.sample, evenly distributed over the surface. Calculate the absolute permeability of the sample when the air-water surface uses 400 seconds to move 18 cm. Water 100 c 82 cm Core sample Additional data Density of water Water viscosity Gravitational constant Thickness of coe sample e Igiee J ep 950
Fluid Pressure
The term fluid pressure is coined as, the measurement of the force per unit area of a given surface of a closed container. It is a branch of physics that helps to study the properties of fluid under various conditions of force.
Gauge Pressure
Pressure is the physical force acting per unit area on a body; the applied force is perpendicular to the surface of the object per unit area. The air around us at sea level exerts a pressure (atmospheric pressure) of about 14.7 psi but this doesn’t seem to bother anyone as the bodily fluids are constantly pushing outwards with the same force but if one swims down into the ocean a few feet below the surface one can notice the difference, there is increased pressure on the eardrum, this is due to an increase in hydrostatic pressure.
