Solar Oven Written Report Lab Example | Topics and Well Written Essays - 500 words

Solar Oven Written - Lab Report Example Internal temperature of the oven cavity normally starts to rise as soon as it is placed in the sun and afterwards reach a constant value known as thermal equilibrium. Consequently, an important activity is to vary the input parameters for the solar oven project and to predict the maximum oven temperature which gives thermal equilibrium. To the developing world, solar oven is an appealing concept given the nature of the energy source. The popularity is attributed to the way energy is harnessed without involving in burning fuels because of it is a renewable source. it’s safe, smoke free which means its eco-friendly, and costs nothing. This makes solar even more reliable because it is plenty in nature and does not require long procedures for obtaining. At thermal equilibrium, basic thermodynamics states that the energy flowing into the oven must be equally balanced by the energy that flows out of the oven and that the power absorbed by the oven equals the power that leaves out of the oven (Sage, 237). This is as illustrated by the following: Goal is to write down equations for both Pout and Pabsorbed, as a function of the design and material properties of our actual oven. Setting these equations equal, we will be able to solve for the internal temperature of the oven in terms of all of these material properties. An equation that is more suitable for our solar oven includes two separate heat-loss terms: a term describing how much heat flows out of the sides and bottom of the oven, and a term that describes how much heat is lost out of the window In this case, a proper design is the use of reflectors, which can perform in increasing the internal temperature of the oven. The reflector increases the temperature through delivering more sunlight to the window and into the cavity of the oven. The significant design constraint considered for the design is that the used reflectors should have flat surfaces and not, in any way, curved surfaces. This is because curved

Alfred Chandlers Assessment of the Managerial Capitalism Literature review

Alfred Chandlers Assessment of the Managerial Capitalism - Literature review Example Chandler’s implied criticism of the organizational theories that existed had a primary place in the consequent growth of organizational theory. Despite the fact that Chandler raised an array of critical questions, his perception of organizations was assaulted from a formidable force of quarters that had a stake in the sociology of organizations. The consequent development in organizational sociology gave a basis for Chandler’s perspective critics to put a case across that discounted the fact that his ideal heroic managers were only part of the story and not the whole story as he had propagated. However, it is important to note that, Chandlers work still offers an insight into the bigger questions and issues, although his perspective with regard to the ultimate role of the organization in the economy is doubtful from the  sociology of organizations point of view. There are three major perspectives of the sociology of organization in the sixties as well as the beginning of the seventies. The interest of all these strands was to discover a science of organizations. As a result of this, none of these points of view saw the difference between organizations, nonprofits as well as government bureaucracies. Moreover, there also was a discrete absence of interest in the historical emergence of corporations. A significant proportion of the sociology of organizations was primarily concentrated on Max Weber’s original formulation of the contemporary bureaucracy (). One strand of the experiential literature was characterized by a positivist inclination. Its major purpose was to discover the extent to which the corporation did or did not match with Weber’s characteristic description (Blau and Scott 1962; Hage and Aiken 1970).Â
