Pressure

Solubility property of ozone is dependent on several extrinsic factors such as temperature, pressure, composition of the medium, pH, gas flow rate, etc. Henry’s law says that the pressure of the gas exerts above the liquid is directly proportional to the solubility of the ozone (Bablon et al., 1991). De Smedt et al. (2001) revealed that solubility of ozone is dependent on pH, temperature and type of additives of the aqueous solution. Levanov et al. (2008) found that solubility of ozone decreased…

A water jet cutter, commonly called a water jet, is a tool that uses a very high-pressure jet of water or a mixture of water and an abrasive to cut a wide variety of materials. A water jet that does not use abrasives is referred to as a pure water jet or water-only cutting [1]. For a pure water jet (Figure 1) the water is pressurized to the range of 20 - 94 ksi, 138 - 649 MPa at the inlet and forced through an orifice with a diameter of between 0.25 - 4 mm creating a very thin high velocity…

It begins on a 6 acre piece of land as an oil rig, with other large machinery and generators. The process includes injecting a mixture of water, sand, and chemicals at a high pressure to break shale rocks and release the natural gas inside. Amongst many shale formations in the U.S., the shale area that spreads from eastern Ohio to western Pennsylvania is called Marcellus. The shale rocks are nearly 5,000 to 8,000 feet underground…

Ferroelectricity Among the ferroelectric materials, the static dielectric constant depends on the temperature under the relation: Curie – Weiss relation: €r = P + Q/ (T-Tc), (T> Tc), P, Q are constants temperature independent. C = Curie constant Tc = Curie temperature A transition in phase is observed at temperature Tc. Above this, the material remains in Paraelectric phase (the phase where the elementary dipoles of different crystal unit cells are…

ulcers Pressure ulcers and Stasis ulcers are usually the popular ulcers when it comes to older adults. Stasis Ulcer is also known as the Venous Stasis Ulcer. Pressure ulcer and Stasis ulcer are two different types of ulcers. Although pressure ulcer and stasis ulcer are common among older adults they are…

students’ immense pressure. It is not an easy experience for even some of the most intelligent people. This has been recognized in history with people such as Albert Einstein, who in 1885, failed his first entrance exam in college. Why did one of the most respected physicians in history not prosper in college? Clearly Einstein had the intelligence. However, there are so many other factors to success in college. Many people would argue that the other biggest factor is the pressure that…

Ultrasonic interferometer Working principle An ultrasonic interferometer is a simple and direct device to determine the ultrasonic velocity in liquids with a high degree of accuracy. An ultrasonic interferometer is used to determine the accurate ultrasonic velocity in liquids. The principle used in the measurement of velocity is based on the accurate determination of the wavelength in the medium. The principle of ultrasonic interferometer for the measurement of velocity is determination of the…

not the only person who experienced pressure from my parents, many of my friends and cousins also have the pressure from their parents with the same ‘love’ excuses. We(Students) already live under the pressure from school, but the parents still add more pressure to the students using the excuse of ‘love’. Maybe the parents really want their children to get better at school, but not everyone has great coping skill to help them to survive under this double-pressure. Once the youth’s coping skills…

In Marge Piercy’s narrative poem, “Barbie Doll”, the story of a young girl is told from the viewpoint of an outside speaker watching her grow up around the norms of society and ultimately ends her life because of it. Throughout each stanza, a new important piece of information is expressed to the readers to contribute to both the theme and tone of the poem. Piercy is able to cultivate the idea that inward beauty is not valued in today’s society, and that artificial perfection can only be…

Coulter Counter Method. Schematic Diagram Diagram 1: The basic setup of coulter counter method. Test tube containing conducting fluid placed in the beaker containing same conducting fluid. Orifice in the test tube connect the circuit. Electrodes are placed in beaker and test tube and voltage is applied. Vacuum is applied in the test tube to allow fluid movement from beaker to test tube. Counting circuit will calculate the amount of particle and pulse height analyser will measure the particle…
