10.3-9 (10-9 in text)The bottom surface of the cylindrical cavity shown in Fig. P10.3-9 is heated to Tbottom= 750°C while the top surface is maintained at Ttop= 100°C. The sides of the cavity are insulated externally and isothermal (i.e., the sides are made of a conductive material and therefore come to a single temperature). top,100 CtopT=°bottom,750 CbottomT=°D= 10 cmL= 10 cmsideFigure P10.3-9: Cylindrical cavity heated from the bottom and cooled on top. The diameter of the cylinder is D= 10 cm and its length is L= 10 cm. Assume that the cylinder is evacuated so that the only mechanism for heat transfer is radiation.
