   1. A 120mm diameter apple (density=990 kg/m3, c=4170 J/kg0C, k=0.58 W/m0C), approximately spherical in shape is taken from a 250 C environment and placed in a refrigerator where temperature is 60 C and average convective heat transfer coefficient over the plate surface is 12.8W/m2 0C. Determine the temperature at the centre of the apple after a period of 2 hours.  2. Explain the following (i) Gray Bodies (ii) Diffuse Emitter (iii) Emissivity  3. Calculate the net radiant heat exchange per m2 for two large parallel plates at temperatures of 4270C and 270C respectively. ε (hot plate= 0.9) and ε (cold plate= 0.6). If a polished aluminium shield is placed between them, find the percentage reduction in the heat transfer. ε (shield)= 0.4  4.
