Abstract
An Air Dehumidifier can be designed and modeled working on simple principle of dehumidification of compressed air by means of collision with the number of cylinders arranged in series. This dehumidifier will not require any hygroscopic media or absorptive media such as Activated Alumina, Silica gel, Salt tablets, etc. which are used in other dehumidifiers. It does not require any refrigerant which is used in the refrigerated dehumidifier. The designed dehumidifier will be most reliable for the point of application. The dehumidifier will be designed to operate at a high pressure of 250 P.S.I. This can be designed as per the as per the theory of thin cylinder. From the design calculations the stresses of the proposed dimensions were

Patrick at Johns Hopkins University, he patented the desiccant kind of material. The material came into existence in 1640’s which was used as the absorptive medium for poisonous gases during the World War-I. This material is generally Silica gel. The desiccant dehumidifier was invented and patented by Hanns F. Arledter, Edward R. Stacy and Clayton E. Bruke in United States on 8th Nov. 1963. While the dehumidifier having deliquescent material was patented by Philip S. Becker in19th April 1996 in United States. This dehumidifier uses hygroscopic media filled in vessel. The material uses salt which have affinity to the moisture. The most common salts are ferric ammonium citrate, potassium hydroxide, etc. The membrane dehumidifier was invented and patented by Ravi Prasad in Praxair Technology Inc. in the year 1993 on 27th April. A two stage membrane dehumidifier employs two stages. The first stage is to remove the water vapor from the air and second stage is to complete the process of …show more content…
Ease in handling. Zero maintenance cost. No moving parts. Economically affordable. High degree of safety.

Article 1 David Nelson Crosthwait Jr was born in Nashville, Tennessee on May 27th in 1898. He is and african american pioneer in the field of heating and air conditioning. He is best known for heating up Radio City Music City in New York City. Crosthwait grew up in Kansas City,Missouri, where he attended all-black school. His parents were very encouraging and challenged him to do experiments and to make designs.
Air pollutants and smog covering the United States in several of the country's largest cities and manufacturing cores provoked the passage of the 1970 Clean Air Act law during the peak of the environmental movement. The Clean Air act is a federal law that limits the number of pollutant emissions by establishing standards that people and companies must meet to ensure public welfare. The Act was put in place to set and meet National Ambient Air Quality Standards (NAAQS) in all 50 states before 1975 in order to eliminate health risks presented by various air pollutants. SIPs, state implemented plan, accompanied the mandate of the NAAQs.
In “Viewpoint: Air-Conditioning will be the end of us,” Eric Klinenberg uses counterargument, personal anecdote, and he provides solutions to help build his argument. He first supplies a personal anecdote in order for the reader to relate more towards him as well as have the reader recount a similar story. He then uses counterarguments in order to show his expertise on the topic. After both personal anecdote and counterargument are used, he follows by supplying solutions in an attempt to persuade the reader more towards his viewpoint. Klinenberg tells the reader of a event that happened to him within the week of writing the article.

The dehydration of 2-methylcyclohexanol takes place at the bottom of the Hickman still. As the Hickman still heats up within the sand bath, the products evaporate and travel higher up in the still where they condense into a liquid and fall within the collection ring, thus separating the product from the remaining water. Drierite (CaSO4) is also added as a drying agent to absorb any leftover water within the product. The purity of the product will then be analyzed with infrared spectroscopy, paying attention to OH peak if it is present. Chemical Reactions: Data and Observations: Material Volume Mol.
Frederick McKinley Jones's invention of the portable refrigeration unit revolutionized the storage and transportation of perishable goods. In the early 1930s, he found the need for a reliable cooling system to preserve food and medical supplies during long-distance transportation ("Frederick McKinley Jones" Biography.com). According to Wikipedia, Jones's
That also goes along with the pricing of items that are made, they are easier and easier

The first step is the pretreatment of the biomass; it includes the grinding of the tobacco to the appropriate size. Subsequently, the biomass is dried as the moisture content of the particle will determine the efficiency of the process. The second step is the Paralysis reaction; the preheated mass is introduced into the paralysis reactor which contains an airlock to keep the oxygen and unwanted air out of the reactor. The combustor preheats the paralysis reactor and heats the biomass indirectly. Paralysis of organic substances produces the gas and liquid product, leaving the solid residue behind.
10 mL of deionized water was added and stirred until fully dissolved. 5.0 mL of 3.0 M of hydrochloric acid was slowly pipetted into the mixture and stirred. The pH was checked to be less than two. The solution was placed into an ice bath to decrease the temperature to 10°C. A vacuum filtration apparatus was built with an Erlenmeyer flask with a vacuum arm and connected to a vacuum source and secured for safety using a ring hoop.
Difference in the mass of the samples will also affect values, as the corrosion rate will vary. Volume of acidic solution Volume of the water was measured in a graduated cylinder. More acidic solution will result in higher rates of corrosion and vice versa Time in acidic solution A stopwatch was used to measure the amount of time each sample was kept in the solution The amount of corrosion will increase as the sample is kept in the solution for longer periods of time. Temperature of Room The temperature of the AC was regulated to be constant.
