The pipe is covered with a 3 cm thick glass wool insulation [k 0.05 W/ m.°C]. Heat is lost to the surroundings at T, = 5°C by natural convection and radiation, with a combined heat transfer coefficient of h, 18 W/m2. °C. Taking the heat transfer coefficient inside the pipe to be h, = 60 W/m2 K, determine the rate of heat loss from the steam per unit length of the pipe. Also determine the temperature drop across the pipe shell and the insulation. Assumptions: Steady state and one dimensional heat transfer. Solution: Taking L 1 m, the areas of the surfaces exposed to convection are: %3D %3D 0,2 %3D %3D
