Consider a conical shaped hollow enclosure. The circular base (radius r = 5 cm) of the enclosure is made of a material with emissivity & = 0.6 and is maintained at 1000°K. The circular top (radius R = 10 cm) of the enclosure is adiabatic. The side of the enclosure is made of a material with emissivity & = 0.7 and is maintained at 500°K. Find the rate of heat transfer from the base to the side of the enclosure. The surface area of the side of the enclosure is given by π(R+r)√(R−r)² + H². Use Stefan-Boltzmann constant o=5.67×10 W/m².Kª. [50 Points] Adiabatic top H = 20 cm T = 1000°K, & = 0.6 T = 500°K, & = 0.7 Consider a conical shaped hollow enclosure.
