MANUAL OF EMISSIVITY MEASURMENT APPARATUS Emissivity Measurement Emissivity is used in equations to calculate heattransfer by thermal radiation. Mechanical Engineering Department Lab Manual Subject -Heat Transfer V Semester List of Experiments: 1. Heat Transfer from a Pin-Fin Apparatus 2. Emissivity Measurement Apparatus. Category: Heat Transfer Lab The 'Swarg Systems & Instruments' apparatus consists of a test plate and a comparator DESCRIPTION: The present Set-up is designed to measure the emissivity of test. STEP 3: Operate the dimmer stat and give the power input to both the plates. The apparatus uses comparator method for determining the emissivity of test plate. It consists of two aluminum plates of equal physical dimensions. Mica heaters Heat Transfer Lab Manual Dr Shah Alam Experiment No. 2 Object: To measure the emissivity of the test plate surface.
