Sadi Carnot, in 1824, explained mathematical principle of refrigeration operation. It was described as a heat engine. In the process of vapor compression refrigeration the refrigerant has to complete phases in cyclic order. In this process, heat is removed and consequently the desired location becomes cool. It is a mechanical process. Indeed, refrigeration system is the process of several refrigeration cycles. It is the widely exploited method for various purposes such as refrigeration,…

Advancements in United States Air Force technology had a tremendous impact on World War II. Without it, the extent of knowledge and capability the Air Force had obtained from the air and on the ground would not have existed. World War II brought enhancements to aircraft, the evolvement of new devices, and much more giving America the edge it needed to rise to the top in World War II. Aircraft was designed and enhanced for optimal performance. Older, upgraded aircraft gained the ability to…

Straight vegetable oils (SVO) are a promising alternative to diesel oil (DO) for diesel engines, due to having comparable properties to mineral diesel, being easy to produce compared to counterparts and offering smaller emissions footprints. Therefore, the experimental study aims to evaluate the potential and influence of Jatropha oil (JO) as diesel engine fuel. Endurance long term operation tests of 300 hours for JO and 100 hours for DO were conducted on a small single cylinder 6.5 kW diesel…

The brain works in mysterious ways. According to Dr. Rita Smilkstein we learn in a series of steps and something as to how you feel when learning something new depends on if you can even remember that knowledge. I believe that the way Dr. Smilkstein explains how the brain works is true compared to some of my own personal stories. According to the research of Dr. Rita Smilkstein, humans learn in five or six stages, which she calls the Natural Human Learning Process (NHLP). This was true of how I…

Four paragraph outline In this essay I will talk about how to properly change the car oil in your vehicle. To start off this is a process that may be time consuming depending on what type of car the work is being done on. Now there are a few steps which I will list 1) first check the car oil and oil filter type. 2) Go out to the automotive store and get the correct oil and oil filter be sure to refer back to your cars manual. 3) Get yourself a foot pound wrench with a standard 14 mm socket. 4)…

Gasometers, also known as Gas Holder’s began their existence around the late 19th century, they were scattered around almost every city and town as a means of storing gas. These structures are made up of a circular metal frame which would hold a piston, this piston would rise and fall due to the amount of gas being stored. Due to more modern and efficient technology gasometers have been left disused and many just appear as large cylindrical scaffolding structures as the tank used is located down…

As many of my friends at Marquette had never been to a Milwaukee Bucks game, I suggested that we went to one as a group. Since everyone was excited by the idea, we went to the next pre-season game. The game was between the Bucks and Pistons. I was extremely excited to go to this game in particular, as I had not been to a game since this spring. Like the college students we are, we got the nosebleed seats, as one can see in the attached photos, but it is still pretty easy to see the action when a…

as double Wiebe function [25, 33]. The direct experimental measurement of heat release rate is difficult. Therefore, a net apparent heat release rate calculated from the experimentally measured pressure-time profile and computationally calculated piston displacement profile along with heat loss to the cylinder wall using equation (1) is applied for validation. The diesel and DME oxidation reaction equations assuming complete…

the playoffs in the second seed. In the first round the Cavaliers defeated the Washington wizards in all four games. In the semi-finals the Cavaliers won 4-2 against the New Jersey Nets. Then in the conference finals the Cavs defeated the Detroit Pistons 4-2. LeBron helped out the team a lot and in the 5th game he scored 48 points with 9 rebounds and 7 assists, and scored the game-winning lay-up. He received a lot of praise from…

engine, it is essential to design a timing drive system to link them together. The design of the timing drive assembly can not only rotate the camshafts, but also required to control the opening and closing of the valves, and the movement of the pistons. For the international combustion engine, there are two main solutions: teethed belt and chain. The crucial function of the timing drive system is to provide drive to the engine’s camshaft(s) and a constant timing relationship to the crankshaft…
