Question

A 250 mm outer diameter steam pipe maintained at temperature 150° C is exposed to an

ambient at 25° C with a convection heat transfer coefficient of 50 W/m2K. Calculate the

thickness of the asbestos insulation (of thermal conductivity 0.1 W/m K) required to reduce

the heat loss from the pipe by 50%.​
