Steam at Tx1 = 320 °C flows in a cast iron pipe (k = 80 W/m. °C) whose inner and outer diameters are
5 cm = 0.05 m and D₂ = 5.5 cm = 0.055 m, respectively. The pipe is covered with 3-cm-thick glass wool
insulation with k = 0.05 W/m. °C. Heat is lost to surroundings at T2 = 5 °C by natural convection and
radiation, with a combined heat transfer coefficient of h₂ = 18 W/m². °C. Taking the heat transfer coefficient
inside the pipe to be h₁ = 60 W/m². °C, determine the temperature drops across the pipe and the insulation.
The determination is based on a unit length of the pipe (L = 1 m).
Assumptions
1. Heat transfer is one-dimensional since there is no indication of any change with time.
2.
Heat transfer is one-dimensional since there is thermal symmetry about the centreline and no
variation in the axial direction.
3. Thermal conductivities are constant.
4. The thermal contact resistant at the interface is…
