A furnace is shaped like a 1-m-diameter and 1-m-long vertical cylinder. The base surface has an emissivity of 0.7 and is maintained at a uniform temperature of 525 K. The side surface has an emissivity of 0.3 and is maintained at a uniform temperature of 600 K. The top surface has an emissivity of 0.5 and is maintained at a uniform temperature of 450 K. If Fbase-top=0.62; Fside-base=0.31, determine the net radiation heat transfer FROM the side surface to the top surface (W). O a. -1986 O b. -1651 О с. -999 O d. 1986 O e. 1651 O f. 999
