WA vertical cylinder 1.75 m tall and 0.3 m in diameter might be used to approximate a man for heat-transfer purposes (thermal conductivity, k-0.8 /m C). Suppose the center temperature of the cylinder is 37 C, the surface emissivity is 0.9, and the cylinder is placed in a large room where the air temperature is 20°C and the heat transfer coefficient is 20W /m"C and the wall temperature is 10°C. 1-Sketch the equivalent thermal resistance network. 2-Neglect the radiation and: -Caleulate the heat lost from the from the cylinder. -Determine the surface temperatures of the cylinder.
