Heat exchanger

result of which an insulation is formed promoting a deeper penetration of heat into the workpiece making a stronger weld joint. The insulation of the flux also prevents the oxides and hydrides from the atmosphere getting trapped into the molten weld pool. The consumable electrode is in the form a wire and is fed automatically through a tube. Electric currents vary from 300 A to 2000 A depending upon the penetration of the heat required. The power supply is most often single phase or a three…

Abstract The paper present the investigation on the effect of temperature, time and current density on surface roughness in electropolishing process on 316L stainless steel. The cathode material under study was 316L stainless steel. The electrolyte was composed of sulfuric acid, phosphoric acid, and DI water. Full factorial design method was used. ANNOVA technique has been used to assess the quantitative influence of the different process factors of the EP. The surface roughness will be…

(tons/year) And N is no. of functional units C = 8300 X 5 X 41200 0.615 = $28 589 719 1.4 Hydrogen storage Hydrogen can be stored either in liquefied or compressed gaseous form. Liquefaction of hydrogen is a costly option. Compressors and heat exchanger cold-boxes account for most of the cost. It is estimated that the total cost for a liquefier is $ 1015 kg/d. Energy consumption by multi stage compression is approximately 10 - 13 kWh / kg of H2. Compressors also play a major role in…

Running about ten miles daily and regular weight lifting is my everyday routine in order to maintain the body that I want…in other words, I love food so I have to work out to be able to continue to fit into my clothes. I always envied my dear friend, Jenny (I envied her in a good way) because she never exercises and cares less about what she eats. One would think that these reasons are grounds for obesity, but not in the case of Jenny. Her body is as beautiful as Jennifer Lopez’s body…even…

(Teslamotors.com, 2015) The Model S is equipped with a 70kWh battery or an 85kWh lithium-ion battery pack (see Figure 10 below), with a Front Radiator and Heat Exchanger that functions as a cooling system for the battery pack (Larsen, 2013). Tesla Model S is activated by a sleek Key Fob (see Figure 11 below), which is designed similarly to the shape of the car. This device comprises of the both the back and front…

lift and drag forces on the surface of the body; generating a vibrational response. This phenomenon plays a significant role in the design of common engineering structures such as bridges, oceanic structures, offshore drilling risers, cables, heat exchangers and numerous other engineering applications. VIV’s have been known to have a detrimental impact on structural fatigue lifespans with the collapse of the Tacoma Narrows Bridge serving as the textbook example. While not solely attributed to…

Future Growth Strategy 1. Capacity Expansion :- Spirotech has recently acquired a 40,000 sq. mt. industrial plot as part of its expansions strategy Construction at the site is expected to begin at the end of July 2011. Operations at the facility are anticipated to start in 2nd quarter of 2012. An additional 200,000 sq. ft. is available for future expansion. Operating capacity to reach 1.5mn units with the commencement of operations at the Kaharani unit in mid 2012. Operating capacity…

2.3 Fats The word fats refer to the lipid food group and it is used to mean both fats and oils. The unseparated fats and oil in foods such as grains, nuts, dairy products, eggs and meats are the example of ‘invisible’ fats that usually more than fifty per cent of our normal fats intake (Ghotra et al, 2002). Fats and oils are calorie-dense food item which give nine calories per gram compared to the carbohydrates and proteins which are four calories per gram respectively. Foods that rich in fats…

Early Atomic Experiments Joseph John Thomson conducted an experiment that is known today as the CRT Experiment. The outcome of this experiment was JJ’s discovery of the electron. CRT is an acronym for Cathode Ray Tube, this gives a broad concept of what the experiment is about. The basic components of the experiment include, a glass cylindrical tube with most of the air inside vacuumed out of it, and inside the tube is Electrode for each side. One of the Electrodes is negative and entitled the…
