a) A 10mm OD pipe has cold fluid flowing inside which keeps the surface temperature at 3C. The pipe is exposed to air at 30C with a convection coefficient of 10W/m2K. Insulation with thermal conductivity of 0.15W/mK is added in 5 mm layers. Investigate the effect of this addition of each layer on the heat flow in. The pipe surface temperature, surrounding temperature and convection coefficients remain unchanged
