CHAPTER 3 METHODOLOGY 3.1 Introduction This experiment is to prove the tile intensity of radiation on a surface is inversely proportional to the square of the distance of the surface from the radiation source. The Radiation Heat Transfer Rig consists of a pair of electrically heated radiant heat and light sources, together with a comprehensive range of targets and measuring instrumentation. The unit consists of a horizontal bench mounted track fitted with a heat radiation source end and a light source at the other. Between the two sources may be placed either a heat radiation detector or a light meter. Distances are measured with a scale mounted on the front track. 3.2 Materials & Equipment Table 3.1 below shows the equipments and the uses of the equipment so that the experiment was conducted smoothly.

"Before using Course Hero my grade was at 78%. By the end of the semester my grade was at 90%. I could not have done it without all the class material I found."

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
