Consider a thick cylindrical wall with insulation at both the inner and outer walls. The inner and outer radii of the thick cylinder are 1₂ = 40 cm and 13 = 80 cm, respectively. The length of cylinder is 1 meter. The thermal conductivity of the wall is k₂ = 120- W mk The thickness of outer insulation is 5 cm and its thermal conductivity is k3 = 12 The thickness of the inner insulation W mk W mk wall k2 = 120 W/mK . The heat r3=80 cm 2 = 40 cm is also 5 cm, but the thermal conductivity is k₁ = 8 dissipates through the surface of outer sides of the insulation W through convention with h, = 50 and the ambient m²K temperature outside the pipe is T = 25°C. The inner most surface is maintained at 80°C. Compute the heat transfer through the wall and the temperature of the outer most surface. Use resistance models to solve this problem. r1 = 35 cm r4 = 85 cm inner insulation k1 = 8 W/mK outer insulation k3 = 12 W/mK
