A fluid at 420 K is flowing inside a 2-in. steel pipe schedule 40. The steel pipe is covered with 10.0 mm of copper and a 20.0 mm outer insulation made up of cork board. The convective heat-transfer coefficient of the gas inside the pipe is 50.0 W/m2K and the convective heat-transfer coefficient of the gas inside the pipe is 25.0 W/m2.K. The ambient temperature outside is 300 K Calculate the heat loss at a 0.800 m section of the pipe using resistances. Compute for the value of Ui based on the inside area Ai
