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
