Example Calculation. Suppose we have a pipe of Diameter 12″ with hot oil at a temperature of 200°C flowing through it. Maximum allowed insulation temperature at the outer wall is 50°C. Allowed heat loss per meter of pipe is 80 W/m. Insulation used is Glass Mineral Wool with thermal conductivity for that temperature range of 0.035W/m.K. Now ...
