feed mixture require to have different volatilities, so they will separate in gas phases when the temperature has reached their boiling points. All in all, distillation is achieved by vaporization and condensation…

ABSTRACT Flakiness & Elongation index is one of the most prominent criteria that govern behavior and performance of aggregate in the bituminous mixes. The strength and serviceability requirements of bituminous mixture such as Stability, Flow, Voids in Total mix (VTM), Voids Filled with Bitumen and (VFB) highly depend on the physical properties of aggregates. This study conducted by observing the effect of flakiness & elongated index by adding different percentages from 0% to 50% of flaky &…

Steel pressure tanks are very strong as they were designed to withstand a great amount of internal pressure. Because of this, it is not unusual to find that many of the larger, steel pressure tanks have been converted into unique structures or repurposed for other uses. Some of the larger steel pressure tanks have been converted into unusual, multilevel round houses. Some of these houses are elevated, while others are ground level or subterranean. Steel pressure tanks have also been adopted…

Through both simple and fractional distillation an equimolar solution of ethyl acetate and propyl acetate was seperated. After distilling 20 mL of the mixture the samples were collected in fractions, which were then analyzed using gas chromatography. The mole ratios of the distillations were converted to a percentage to analyze percent composition. Simple distillation yielded the following results: S1- 69.88% EA/ 30.12% PA, S2- 66.73% EA/ 33.27% PA, and S3- 46.42% EA, 53.58% PA. Fractional…

If you’re a long time sufferer of back pain or you’ve been looking for laser spine surgery in LA but are still having reservations about a relatively new surgical method, here are some facts about laser spine surgery to give you peace of mind and help you make an informed decision: Fact 1: Lasers only play a small role in the procedure. The main role of the laser is to act in place of the scalpel used in traditional surgery to make incisions. The rest of the surgery is generally carried out with…

The Effect of Cellular Respiration at Low and High Temperatures Introduction Cellular respiration can include two processes, aerobic respiration and anaerobic respiration. The main purpose of cellular respiration is to breakdown sugars into smaller structures so that the cell can use it as energy (Reece, et al. 2014). The main concept of the respiration lab is aerobic respiration. This is the process that organic compounds will be degraded from oxygen to produce water, carbon dioxides, and…

At the point when the subject of an Earth-wide temperature boost arises during natural discourse many individuals either moan and dodge discussion, or wear their dueling gloves and get ready for a warmed verbal confrontation. A few people feel regretful and concerned; some basically couldn 't care less. Distinctive perspectives yield diverse positions on the subject. Originating from the logical and ecological perspectives, myrmecologist Edward O. Wilson examines the seriousness of a worldwide…

Principle components of Rankine cycle: The four basic components of Rankine cycle are shown in figure 1 each component in the cycle is regarded as control volume, operating at steady state. Pump: The liquid condensate leaving the condenser at the state 1 is pumped to the operating pressure of the boiler. The pump operation is considered isentropic. Boiler: The heat is supplied in the working fluid (feed water) in the boiler and thus vapour is generated. The vapour leaving the boiler is wther…

1873. The van der Waals EOS gives a simple, qualitatively accurate relation between pressure, temperature, and molar volume. P=RT/(V-b)-a/V^2 where a is “attraction” parameter, b is “repulsion” parameter, and R is universal gas constant. Comparing this equation with the ideal gas law,P= zRT/v, we see that the van der Waals equation offers two important improvements. The prediction of liquid behavior is more accurate because volume approaches a limiting value 'b' at high pressures i.e,…

fixed mass of gas held at a constant volume, which pressure divided by temperature is a constant value. The gas has initial pressure and final pressure of Pi and Pf respectively, and initial temperature and final temperature of Ti and Tf respectively. Therefore, the equation below is obtained: Pi/Ti=Pf/Tf Where, Pi = Initial pressure Pf = Final pressure Ti = Initial…
