A gas at 450 K is flowing inside a 2-in steel pipe, schedule 40. The pipe is insulated with 51 mm of lagging having a mean k=0.0623 W /m*k. The convective heat transfer coefficient of the gas inside the pipe is 30.7 W/m?Kand the convective coefficient on the outside of the lagging is 10.8. The air is at a temperature of 300 K. a. Calculate the Heat Loss per unit length of 1 m of pipe using resistances. b. Repeat using the overall U, based on the outside area A..
