Air enters a 2.54-cm-OD, 1.9-cm-ID steel pipe at a velocity of 1 m/s and a temperature of -7C. The outside ambient air is at 21C and has a dew point of 10C. Using COMSOL Multiphysics: Determine how much insulation (k=0.18 W/mK, Cp= 1600 J/kg.K, p = 1300 kg/m) is needed to prevent condensation at any point along the exterior wall of the insulation if h =2.4 W/mK on the outside? Plot radius of the insulation vs outside insulation surface temperature. Assume pipe length is 20 cm.
