Answer to Question #187623 in General Chemistry for Joyel Thomas

Question

A tube of 60-mm outer diameter (OD) is insulated with a 50- mm layer of silica foam, for which the conductivity is W/(m · ℃ ), followed with a 40-mm layer of cork with a conductivity of 0.05 W/(m · ℃ ). If the temperature of the outer surface of the pipe is 150 ℃ and the temperature of the outer surface of the cork is 30 ℃, calculate the heat loss in watts per meter of pipe

Answer 1

Heat loss=41.5 W/hr
