A 1 inch Schedule 10 copper pipe carries 10 GPM of brine at -5 degrees C. The ambient air is at 20 degrees C and has a dewpoint of 10 degrees C. How thick a layer of insulation of thermal conductivity 0.2 W/mK is required to prevent condensation on the outside of the insulation? Take the outside heat transfer coefficient as 11.0 W/m^2K.
