Porous Media Are A Material Having Minute Interconnected Voids

3219 Words13 Pages

POROUS MEDIA
Porous media are a material having minute interstices through which liquid or air may pass. It is nothing but the media having interconnected voids. It can be soil, aquifer, reservoirs, rocks, stone, sponge, zeolite, ceramic, biological material like wood or any other material which allows to pass air or water through it. Its structure is like the solid skeleton and voids connected to each other throughout the medium.
It may categorize into various classes such as: Saturated porous media Unsaturated porous media Consolidated porous media Unconsolidated porous media.
It may again categorized on the basis of its structure Rigid frame porous media
: It is the material formed by a number of pore4s within a rigid solid. Limp frame porous media
: It is similar to the rigid frame assumption, but removed framed dynamics. Elastic frame porous media
: It is more valid as it includes the frame motion.
It turns out that three waves exist in a Poro-elastic material. (M.R.F. Kidner)
Many researchers have studied the porous media in order to predict the characteristics of it such as pore network, air and water permeability, saturation, consolidation etc. porosity is the main characteristic of porous media by which it has acquired its name. Some researchers have studied the permeability, electrical …show more content…

(1956 a,b). after him many reserachers relates and given the various equation to realte the soil properties with the seismic response of porous media. Seismic waves mainly consists of P wave and S wave ot of which P wave is capable of travelling through both the solid structure of porous media and fluid flowing through it. Where S wave is capable of travel only through solid structure or in other words it travels particle to particle. Because of these properties of P and S waves it is possible to characterize the porous

    The three most important properties of a wave are the wavelength, the amplitude, and the frequency. The wavelength is the distance from one point on a wave to the next identical point on the next wave. The amplitude is the distance from a waves rest position to either the crest or trough of the wave. The frequency is a rate which represents the amount of times a wave repeats

    Since the bog is home to many types of rare plants, its ecological strucuture is quite unique and special. In particular, the sphagnum moss absorbs and holds moisture that is slowly released into the atmosphere. Because sphagnum is very water absorvant, acidic, and antiseptic, it has had many significant benefits to the Musqueam People, such as using the moss to disinfectant bandages and baby diapers. Of particular notice is the importance of water in the bog: water released in the bog is acidic, and it acts like a solution that prevents bacterial growth, slows decomposition, and reduces nutrition availability. In addition, dead/decayed plants create carbon sink: a natural or artificial reservoir that accumulates and stores some carbon-containing chemical compound for an indefinite period.

    Summer Reading Essay: The Color of Water James McBride turned out to be a very good man although his outside influences growing up would encourage the opposite.

    The mechanical vibrations transmitted through a medium; solid, liquid or a gas generates a sound wave. The sound is an energy, which deflects the particles of a medium in the same direction, and itself travel as a longitudinal waveform with areas of compression and rarefactions. The image generated by ultrasound is essentially based on similar principle by means of a machine, which includes an ultrasound transducer and a screen. The transducer contains a piezoelectric crystal made up of lead zirconite, which generates an ultrasound beam on applying an electrical current to the transducer. These signals travel through a medium in the body and after striking with various tissues, return back to the transducer.

    The purpose of this lab was to observe the phenomenon of resonance in an open ended cylindrical tube and use resonance to determine the velocity of sound in air at regular temperatures. A hypothesis for this lab was that if the frequency of the tuning fork increased, then the length of the tube to achieve resonance will increase because of the high amplitude of the vibration. The resonance of the open-closed tube was found through these steps. First, the tube was filled with water with an inner tube inside the outer tube. The water temperature was measured.
