Under Pressure

them the reason she took her own life. Mirikatini writes this note from the young Asian-American’s pressure-filled mind who has battled with the feeling of being “not good enough” for too long. This poem is filled with many comparisons and analogies that descriptively illustrate what the girl that Mirikitani writes about was thinking and feeling. The suicide note displays the overwhelming pressure that young adults feel from their families and friends, how prevalent suicide is in today’s society…

liquid and its velocity. The capillary pressure at porous media is defined as the difference between pressure in the liquid and vapor phase. Mass conservation for liquid phase is as follow: (18) (∂(εsρ_l))/∂t+∇.(ρ_l u ⃗_l )=S_(g-l) Darcy law can be used for liquid momentum equation in porous media; therefore, momentum equation is reduced and can be expressed by: (19) u ⃗_l=-K_l/μ_l ∇p_l Also, the liquid pressure can be extracted from definition of capillary pressure. (20) p_c=p_g-p_l=f(s)…

October 2016 College Pressures College is a time of anxiety and panic for many students all over the world. In the piece, “College Pressures” by William Zinsser, there is talk about the pressures of college and advises how to handle these moments of breakdown. Through the late nights and tears shed, you have feelings of high doubt and stress. Zinsser points out the four main pressures of college as being “economic pressure, parental pressure, peer pressure and self-induced pressure” (275). The…

experiments on pressure systems conducted, the Marcet boiler and Boyle’s law. The aim of this lab is to investigate in pressure-temperature relationship, Boyle’s law, as well as steam quality. The results of this experiment support both relationship, as well as successfully providing a value for steam quality. For the Marcet boiler experiment, it was found that the higher the system pressure, the higher the saturated temperature. For the Boyle’s law experiment, it was found that pressure is…

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…

Pressure vs. Volume and Boyle’s Law Pre-Lab Questions According to our modern understanding of the gas laws, there are four measurable properties (variables) of a gas. These variables are P (pressure), V (volume), T (temperature), and n (number of moles). In Boyle’s experiment, which two variables were held constant? Both the temperature (T) and the number of moles of gas (n) were held constant in Boyle’s experiment. Fill in the blanks to summarize the relationship among the gas properties in…

affect air pressure. In the experiment, the basketball was measured in four different temperatures. Therefore, the basketball was dropped at a certain height. The results were as the temperature increases, the bounce of the basketball increases. If you ever played a sport, or drove a car, you probably never thought if on a cold day would it ruin a ball, or flatten your tire. Maybe on a hot day, the temperature can affect how high it would bounce. How does temperature affect air pressure?…

exerted fixed mass of gas at a constant temperature and V, the volume have a relationship. Their kind of relationship is V=f(P) relationship and it is believed that PV go together to remain constant. A water manometer is an instrument used to measure pressure. The model of kinetic theory of gases helps elaborate one of the most difficult…

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…
