A researcher tries to apply a 5mm thick cure-on epoxy insulation to an internally-heated spherical container, but the epoxy delaminates. The container (ID = 30mm, OD = 50mm) is made of 18000W aluminum and has a heat flux on the internal surface of qim If the epoxy delaminates at m²K W 40 200°C, what is the minimum required air temperature if hair to make this occur? m²K
