Question

A copper pipe having 35 mm OD and 30 mm ID carries liquid oxygen to the
storage site of a space shuttle at -182°C and 0.06 m3/min. The ambient air is at
20°C and has a dew point of 10°C. How much insulation with a thermal
conductivity of 0.02 W/(
mK) is needed to prevent condensation on the exterior
of the insulation if the convective heat transfer coefficient h = 17 W/(m2K) on
the outside? Take thermal conductivity of copper kCu = 400 W/(mK). 3
